RF front ends (transceivers) for Broadband Multimedia (TV, CATV, DBS Satellite and MoCA Home Network-ing) have been developed in our group at Broadcom since 1998. This talk will discuss the evolution of Broad-com’s integrated broadband RF technology from our first standalone CATV tuner (BCM3415 in 0.35m CMOS) through System-on-Chip embedded zero-IF tuners to our latest technology direction: direct-sampled RF trans-ceivers in 40nm with digital channelization and digital correction of analog non-idealities. There will also be an overview of the consumer applications that are served by this technology.

Broadcom is one of the largest IC companies in the world and is the largest fabless IC company by IC revenue, with approximately 10,000 employees worldwide. Broadcom’s technology portfolio includes all key consumer communication standards: 2G through 4G cellular, WiLAN, Bluetooth, 60GHz, GPS, TV, satellite, MoCA net-working, DSL, power-line, 10-100-1000-10G-40G Ethernet, network switching, high-speed SerDes, power management, touch controllers, high performance embedded processors and more.


Ray Gomez received the B.S. degree in Biomedical Engineering from Case Western Reserve University in 1981, the M.S.E.E. degree from Stanford University in 1982, and the Ph.D. degree from UCLA in 1993. He worked at TRW in Redondo Beach, CA from 1982 to 1986 on high-performance radios for aerospace applica-tions. From 1993 to 1995, he was a member of the disk-drive read channel design team at Cirrus Logic in Aus-tin, TX.

Ray joined Broadcom in Irvine, CA in 1995, where he has focused on CMOS RF circuits for cable and broad-cast television tuners; DBS satellite set-top box tuners, and more recently, MoCA home multimedia networking. Broadcom’s Broadband RF team developed the first silicon CMOS integrated TV tuner and the first television and satellite set-top box tuners integrated into CMOS system-on-chip devices, and is now pioneering direct sampling RF design using data converters. Ray’s team presently has more than 60 designers worldwide, and has achieved outstanding market success, selling hundreds of millions of units worldwide.

Ray was named a Broadcom Fellow in 2006 for his contributions to tuner design, and has numerous IEEE publi-cations and over 60 issued patents. He is an IEEE Senior Member
