Axiom Microdevices to Participate in the 2008 International Solid State Circuits Conference

Dr. Ali Hajimiri, Axiom Co-Founder, to Present a Technical Paper Entitled "A Fully-Integrated Quad-Band GSM/GPRS CMOS Power Amplifier"; Donald McClymont, Vice President of Marketing, to Make a Presentation Entitled "CMOS PA Integration and Future RF Front-End Integration"

IRVINE, CA--(Marketwire - January 16, 2008) - Axiom Microdevices Inc., provider of the world's first and only fully integrated complementary metal oxide semiconductor power amplifiers (CMOS PA) for mobile handsets, today announced participation in the 2008 International Solid State Circuits Conference (ISSCC), taking place February 3-7 in San Francisco, Calif.


Axiom Microdevices Inc. is a supplier of fully integrated commodity complementary metal oxide semiconductor power amplifiers (CMOS PA) to the worldwide mobile handset market. The company's patented technology offers the latest advances in radio frequency integration, enabling customers to reduce design complexities and bill of materials, while optimizing performance and guaranteeing supply continuity. Axiom Microdevices has its headquarters in Irvine, Calif., with sales representation in the United Kingdom, China, Taiwan and South Korea. For more information, please visit us at


As part of the technical sessions at ISSCC, Dr. Ali Hajimiri, co-founder and chair of Axiom's Distinguished Technical Advisors, will present a paper on "A Fully-Integrated Quad-Band GSM/GPRS CMOS Power Amplifier." The purpose of this paper is to outline how Axiom has been able to implement a fully-integrated quad-band power amplifier, with integrated input and output matching and on-chip closed-loop power control and supply from 2.9 volts (V) to 6V using standard 130nm CMOS.

In addition to the above technical presentation by Axiom, Donald McClymont will participate in a panel discussion entitled "From Silicon to Aether and Back," where he will also present a paper on the topic of, "CMOS PA Integration and Future RF Front-End Integration." As part of the session, McClymont will assert that volume of investment and economies of scale make the standard CMOS process the perpetual cost leader. With greater than one billion units produced per year, the cell phone market is the largest and most competitive that the semiconductor industry has to address, and as such, CMOS provides the lowest cost path to product, assuming the technical hurdles of implementation can be crossed. To date, the power amplifier block has required the use of specialty GaAs or LDMOS processes coupled with a hybrid module packaging technology in order to realize the matching circuitry. Axiom Microdevices, with its distributed active transformer (DAT) technology has developed a 50-ohm matched power amplifier (PA) product in bulk CMOS without the use of a module technology, which is now shipping in high volume. During this discussion, McClymont will discuss the CMOS PA and introduce the possibility of its further integration with other elements of the block diagram in order to provide even more advantages in both cost and performance. Dr. Ali Hajimiri, Axiom's co-founder and Chair of Axiom's Distinguished Technical Advisors, will chair the discussion.

ISSCC is the foremost forum for presentation of advances in solid-state circuits and systems-on-a-chip. The Conference offers a unique opportunity for engineers working at the cutting edge of IC design and use to maintain technical currency, and to network with leading experts.


Axiom Microdevices' award-winning CMOS PA integrates full quad-band GSM/GPRS functionality on a single integrated circuit, using mainstream 0.13um silicon CMOS technology. This patented technology enables integration of the PA output match on die along with the power control function, eliminating the need for complex and expensive multi-chip module technology based on GaAs or other specialty processes. With the implementation in Silicon of the last component of the phone, Axiom has opened up the path to integration of the entire radio function on die. This re-partitioning of the cellular system will result in significant future opportunities in cost reduction due to architecture simplification and hardware reuse as well as allow the implementation of reconfigurable radios that can adapt to their operating modes. Axiom Microdevices is now shipping over a million PAs a month as it continues to ramp its production at multiple customers and in multiple handsets.
