In 1991, only a few individuals had Internet access. Those that did submit in on-line boards or electronic mail associates from dwelling usually accessed the Internet through phone line, their messages touring at a prime velocity of 14.4 kilobits per second. In the meantime, cable TV was rocketing in reputation. By 1991, sixty percent of U.S. households subscribed to a cable service; cable rollouts in the remainder of the world had been additionally selecting up velocity.
Hypothetically, utilizing that rising cable community as a substitute of telephone strains for Web entry would dramatically increase the velocity of communications. And making cable TV itself digital as a substitute of analog would enable cable suppliers to hold many extra channels. The idea of how to do this—utilizing analog-to-digital converters and digital signal processing to translate the analog waveforms that journey on coaxial cable into digital kind—was effectively established. However the cable modems required to implement such a digital broadband community weren’t on the mass market.
Enter Henry Samueli. In 1985, he had established a multidisciplinary analysis program on the College of California, Los Angeles, to develop chips for digital broadband. Over the subsequent a number of years, he and his staff created all kinds of proof-of-concept chips demonstrating the important thing constructing blocks of high-performance digital modems. And in 1991, Samueli, alongside together with his UCLA grad pupil Henry Nicholas, based Broadcom Corp. to commercialize the expertise.
At present, the improvements in digital signal processing architectures pioneered at UCLA and Broadcom persist within the digital modems that allow each wired and wireless communications in our units. For these advances, together with contributions to increasing science, expertise, engineering, and math (STEM) training, Samueli is the recipient of the 2025 IEEE Medal of Honor.

Earlier than the Cable Modem—Approach Earlier than
Samueli began down the trail that may result in cable modems when he was in center college. However he wasn’t occupied with a future profession when he enrolled in an electrical store class. It was simply that, he says, “electrical energy appeared form of mysterious, in contrast with metallic or wooden.”
The instructor assigned a crystal radio challenge, he remembers, “however wrapping a wire round a tube from rest room paper and connecting the wire to a crystal wasn’t that thrilling to me.” So he thumbed via an electronics catalog in search of an alternate. A
Graymark five-tube radio caught his eye. It took some convincing earlier than the instructor agreed to let him deal with the challenge, which got here with sophisticated directions and concerned studying the right way to solder.
“I labored each evening,” Samueli says. “There have been tons of of connections that I needed to solder up. It took a full semester to construct it, and, on the finish, I introduced it into class, plugged it in, and sound got here out of it. I used to be completely blown away. And I actually made it my mission in life to determine how radios work.”
Samueli’s instructor was blown away as effectively. And what he mentioned crystallized Samueli’s future. “He informed me, ‘Henry, actually, I by no means ever thought you possibly can do that. However clearly, you’ve acquired some particular presents. I believe you must pursue electrical engineering as a profession. You’re going to do one thing huge sometime.’ ”
UCLA Takes Maintain—and By no means Lets Go
Samueli ultimately utilized to UCLA—a college with electrical engineering program and inexpensive tuition that was near dwelling. He went straight via to a Ph.D. however, he says, didn’t actually perceive how radios labored till just a few years past that.
After amassing his Ph.D. in 1980, Samueli joined TRW to work on protection communications tasks. He says he liked each minute. “It’s an amazing alternative to study since you’re coping with superhigh tech, the best expertise on the time. And with an enormous funds, you may construct very refined issues,” he says.

Samueli didn’t fully go away the world of upper training. In his spare time, he taught a circuit-design class at
California State University, Northridge, after which a number of circuits and sign processing lessons at UCLA. In 1985, UCLA provided him an assistant professorship, and he left TRW, taking coworker Henry Nicholas with him as his first Ph.D. pupil.
The 2 shaped the core of what would change into the multidisciplinary communications analysis program in UCLA’s Built-in Circuits and Programs Laboratory. They collaborated with a number of school members within the electrical engineering and pc science division to develop digital modem chips.
“Chip design is a really advanced and broad self-discipline,” Samueli factors out. “There are analog designs, digital designs, a number of methods, varied architectures. Whereas such a multidisciplinary strategy is normal right this moment, it was pretty uncommon on the time.”
AT&T Bell Labs was main the world in digital-communications analysis, Samueli remembers, utilizing low-speed modems that communicated in the identical bandwidths because the human voice. The labs constructed these modems utilizing programmable digital sign processing chips from
Texas Instruments and others.
“It was a software-driven strategy to constructing digital sign processing,” Samueli says. “And it solely ran at data rates of tens of kilobits per second. Our problem was the right way to take these algorithms and make them run at tens of
megabits per second—one thousand occasions sooner.”
Samueli and his colleagues concluded {that a} programmable structure utilizing software program was simply too gradual. In order that they started investigating parallel architectures that might implement refined algorithms on a single chip with no software program, simply devoted {hardware}. “That was our innovation. Again then, it was very novel,” he notes. “At present, it’s what makes AI processors work.”
UCLA researchers who specialised in analog sign processing collaborated with the group to combine high-speed analog-to-digital and digital-to-analog converters into the core features of the chip—“actually breakthrough work,” Samueli says.
“I used to be completely blown away. And I actually made it my mission in life to determine how radios work.”— Henry Samueli
Samueli and his staff weren’t pondering patents whereas they had been doing this analysis. As lecturers, their focus was on publishing their outcomes—some 100-plus papers over 10 years. However many others noticed industrial potential of their work.
“After we’d publish a paper, we’d go to a convention and make a presentation,” Samueli says. “Folks would come as much as us after the discuss and say, ‘That is actually neat stuff. Have you ever ever thought of commercializing it and beginning an organization?’”
Samueli and Nicholas took the leap in August of 1991, incorporating Broadcom Corp. and chipping in US $5,000 every to lease an workplace and purchase computer systems and workplace provides.
Samueli saved working full-time at UCLA whereas Broadcom started bringing in small protection contracts: growing a digital frequency synthesizer for TRW, a digital filter for a Rockwell microwave radio, and, for the U.S. Air Pressure, a digital filter to guard GPS alerts from jamming.
“These tasks funded our R&D, and we gained increasingly more data,” says Samueli. [For more on Samueli’s early career, see this 1999 profile.]
Scientific Atlanta Connects with Broadcom
In December 1992, a pupil of Samueli’s
gave a presentation at Globecom (the IEEE World Telecommunications Convention, that’s) a few prototype 10-plus megabit-per-second digital modem chip the group had developed.
“What was totally different of their chip is that it built-in digital and analog,” remembers Leo Montreuil, then an engineer at
Scientific Atlanta and now an IC design engineer at Broadcom. On the time, Scientific Atlanta shared the U.S. cable TV set-top field market with just one competitor, General Instrument. “We had many corporations making chips for Scientific Atlanta, however not that form of chip.”
After the presentation, Montreuil approached the scholar, who referred him to Samueli. Montreuil met with Samueli and Nicholas three months later.

Scientific Atlanta wasn’t simply casually curious in regards to the work. The corporate had signed a serious contract with Time Warner to construct 4,000 set-top packing containers for the world’s first digital cable system, known as the
Full Service Network. It wanted a digital modem for that field, however the needed chips weren’t commercially accessible.
“What they had been making an attempt to do in a single chip appeared so a lot better than multichip methods being developed by others,” says Montreuil. “Whenever you go from analog to a digital implementation, you need to fear about drift, temperature sensitivity, and different points. The extra you may implement within the digital area, the extra predictable is the system.”
Scientific Atlanta awarded a $1 million growth contract to Broadcom in June of 1993. Though Broadcom’s design ended up utilizing three chips, the corporate did mix analog and digital circuitry on the identical silicon.
“The challenge was easy,” Samueli says, “as a result of it was based mostly on the prototype designs we had already performed. And it labored the primary time, flawlessly.”
Time Warner’s digital cable community—activated in Orlando, Fla., in early 1995—was a technical success, however Time Warner didn’t take it any additional. The community wasn’t meant to be financially viable, Montreuil says, stating that the core of every dwelling system was a prohibitively costly Solar SPARC workstation. “The aim was to accumulate data and to get our foot within the door for the subsequent technology.”
Broadcom’s modem design impressed each Scientific Atlanta and Common Instrument. The 2 rivals invested $1 million every, for a ten p.c whole stake within the startup. That funding allowed Broadcom to maintain engaged on digital modems, to scale back the price by placing all of the features on a single chip.
Sherman Chen was a senior engineer at Common Instrument on the time. “We knew then that the Broadcom gadget would dramatically lengthen the boundaries of communications,” remembers Chen, who’s now vp of engineering in Broadcom’s broadband video group. “Concepts like superior error correction and digital compression had been round, however they had been all simply elegant theories till Broadcom constructed the primary mixed-signal silicon for broadband communications. Broadcom created an business.”
Broadcom wasn’t the one firm chasing the low-cost digital modem grail. One key competitor was LANcity, which had a $500 digital modem. The market was evolving shortly, and it was changing into clear to cable operators that this new expertise would require standardization. Broadcom, CableLabs, Common Instrument, LANcity, 3Com, and others
began collaborating in 1995 to create a world normal known as the Data-Over-Cable Service Interface Specification (DOCSIS).
“Folks would come as much as us after the discuss and say, ‘That is actually neat stuff. Have you ever ever thought of commercializing it and beginning an organization?’ ”— Henry Samueli
Round that point, Samueli left UCLA to concentrate on Broadcom, which had lately moved from Los Angeles to Irvine, in Orange County. Reluctant to chop his tutorial ties, he requested that his departure be thought of a brief go away of absence. He formally stays on go away from UCLA even now.
In 1995, Broadcom launched its first mainstream industrial product—that’s, a tool constructed to promote on the open market, not developed below contract. The BCM3100 was an under-$20, single-chip, DOCSIS-compatible digital modem. In 1996, Broadcom added one other sort of product: digital Ethernet chips, what Samueli says was the world’s first all-digital implementation of Ethernet expertise. With these two profitable product strains, Broadcom went public in 1998 at a valuation of $1 billion, making Samueli, Nicholas, and lots of of Broadcom’s 320 or so workers rich. By mid-2000, that valuation had jumped to greater than $60 billion, with Samueli’s stake price about $10 billion, and, based on the
Orange County Register, the typical worker price almost $6 million.
“We had been a really beneficiant firm to our workers,” Samueli says. “We gave inventory to just about everyone within the firm. We had it to present as a result of we didn’t dilute our shares by taking up venture capital buyers.”
The SEC Goes After Broadcom’s Inventory Choice Grants
This sharing of the wealth, paradoxically, led to one of many darkest chapters in Samueli’s story. Within the mid-2000s, the U.S. Securities and Trade Fee started investigating using inventory choices at quite a few tech corporations, together with Broadcom. The SEC opened a proper inquiry into Broadcom’s practices in late 2006 and in 2008 charged a number of Broadcom executives, together with Samueli and Nicholas, of backdating inventory choices.
“It was a nightmare,” Samueli says. “We went via 5 years of hell. It’s horrifying. They threaten you. They are saying, ‘We’re going to place you in jail for 300 years.’ ”
In late 2009, the case got here earlier than U.S. District Court docket Choose
Cormac Carney. After listening to a few of the proof, together with testimony from Samueli and others, the decide “threw all the pieces out,” Samueli says.
Carney appeared significantly outraged by the prosecution’s therapy of Samueli.
His ruling stated: “The uncontroverted proof at trial established that Dr. Samueli was a superb engineer and a person of unimaginable integrity. There was no proof at trial to recommend that Dr. Samueli did something unsuitable, not to mention felony. But, the federal government launched into a marketing campaign of intimidation and different misconduct to embarrass him and produce him down.”
Says Samueli: “This complete choices backdating scandal was distress, however I wouldn’t change what we did. I believe being overly beneficiant to workers is an efficient factor.”
In the meantime, Broadcom cofounder Nicholas was struggling. He had resigned from the corporate in 2003, and across the similar time because the inventory choices investigation, he was indicted for distribution of unlawful medication. Nicholas entered rehab in 2008, and
the charges were eventually dropped. A decade later, although, Nicholas was arrested in Las Vegas for drug trafficking and took a plea deal with out admitting guilt.
“I haven’t spoken to him in a few years,” says Samueli. “It’s actually unhappy. However what he did for the corporate can’t be underestimated. I want him all the perfect.”
Samueli’s Philanthropy and the Giving Pledge
Samueli remained a gentle presence as Broadcom’s chief expertise officer till 2018, persevering with via its acquisition by Avago in 2016. (The ensuing entity is now known as
Broadcom Inc.) Since 2018, he’s served as chairman. He nonetheless has an enormous affect on the corporate’s engineers. Charlie Kawwas, president of Broadcom’s semiconductor options group, says that Samueli continues to attend all the division’s technical evaluations—about 72 a 12 months, every lasting 2 to three hours.
“He engages with the engineers, asking questions and giving suggestions, and so they love that,” Kawwas says.

Together with his present private wealth
estimated by Forbes at about $20 billion, Samueli spends a lot of his time giving money away via the Samueli Foundation. He additionally chairs the board of the Broadcom Foundation. He and his spouse, Susan, have dedicated to the Giving Pledge, promising to present away most of their wealth both throughout their lifetimes or of their wills.
“After Broadcom went public, and the inventory was flying, Susan and I made a decision we wanted to start out giving this away. It was straightforward to think about what I wished to present again to. What created this wealth? My engineering education. And UCLA was that whole training—my bachelor’s, grasp’s, Ph.D., school member. So there was no query in my thoughts that the primary main present could be to
UCLA and the engineering school, and that was $30 million in 1999.” [See “Henry Samueli’s Career Advice for Aspiring Engineers.”]
Since then, the Samueli Basis has supported engineering and integrative well being applications at UCLA and the College of California, Irvine, for a complete, Samueli estimates, of greater than $500 million. (Integrative well being is well being care that embraces various therapies together with standard drugs and is a ardour of Samueli’s spouse.) The muse additionally targets tasks geared toward bringing college students into the STEM pipeline, together with making a constitution center and highschool—
the Samueli Academy—centered on hands-on studying in engineering and design arts. It’s working with group faculties to increase coaching for nursing, building, maritime, and STEM careers. And the muse funds initiatives to fight antisemitism and to advertise collaborations with Israel and tasks inside Israel, a rising focus in response to current occasions.

Altogether the muse has distributed greater than $1 billion thus far, and it’s on observe to present away a few billion extra on this decade, experiences
Lindsey Spindle, president of the Samueli Household Philanthropies, which oversees the muse and the household’s different, smaller philanthropic efforts.
“Henry’s engineering background offers him the fitting structure for philanthropy,” Spindle says. “He is aware of about methods constructing. He appreciates interconnectivity. If you end up constructing {hardware}, you need to take into consideration the bigger system through which it’ll perform, be affected person, and be keen to iterate. Whenever you care about combating antisemitism, ending homelessness, and reorienting drugs in the direction of well-being, you additionally need to have a methods orientation and be keen to iterate.”
This 12 months’s IEEE Medal of Honor comes with a major money award—
$2 million, up from $50,000 within the current previous. Samueli, an IEEE since his pupil days and now an IEEE Fellow, plans to make use of the cash to create an endowment to allow IEEE’s Eta Kappa Nu honor society to host an annual student-leadership convention, one thing he’s been funding instantly for the previous three years.

Samueli can also be the proprietor of the Nationwide Hockey League franchise the
Anaheim Ducks. At a look, this would possibly look like a typical wealthy man’s plaything—and there’s no doubt that he enjoys his involvement with the staff. However the acquisition got here from an impulse to do good. In 2003, the corporate managing the Geese’ dwelling, the Anaheim Area, went bankrupt. Anaheim officers knew Samueli was an energetic businessman within the Ocean County group, and so they requested him to take over administration of the world (now known as the Honda Heart). In the meantime, Geese proprietor Disney was desirous to promote the staff.
Says Samueli: “In worry of an outsider coming in and transferring the staff out of city, we determined that, for the group’s sake, we might make certain they keep right here—and learn to run a sports activities staff.”
“It was an enormous studying curve,” he says. “However in any enterprise, it’s actually in regards to the administration. We put in administration staff—and gained the Stanley Cup in our second 12 months of possession.”
His dive into studying about hockey is attribute of Samueli’s strategy to only about all the pieces, individuals who’ve labored with him report.
“Henry has a seemingly limitless capability to entertain new concepts,” Spindle says. She described a visit to Antarctica, for which her household joined a few of the Samuelis. “Henry went to each lecture provided on the ship. He went on each tour,” she says. In his work with the muse, she continued, he’s equally curious and engaged. “He exhibits up at each assembly,” she says. “You’ll be able to ship him a 120-page doc, and he’ll learn each phrase and are available ready to ask questions.”
The hockey staff is a part of Samueli’s funding in, and delight of, the Orange County group. Subsequent up is creating a real downtown Anaheim, within the type of an arts and leisure district tagged
OCVIBE. And in his free time, he takes lengthy e-bike rides simply to benefit from the neighborhoods.
“OCVIBE and the Geese are an essential a part of our lives,” Samueli says. “And as Broadcom inventory grows, we simply preserve placing increasingly more cash into the muse. That’s not going to cease. Then, after all, there’s being on the Broadcom board and deeply concerned with Broadcom—I can see that persevering with for a few years. Theoretically, I’m retired, however I’m as busy as ever.”
