MICRO LINEAR SELECTS JAZZ SEMICONDUCTOR AS FOUNDRY PARTNER FOR NEXT GENERATION PHS TRANSCEIVER

Jazz Semiconductor's Advanced SiGe BiCMOS Technology and Design Platform Leveraged to Create
Highly Integrated Single Chip 1900MHz Solution

SAN JOSE, Calif. and NEWPORT BEACH, Calif., April 12, 2005 -- Micro Linear (Nasdaq: MLIN), a developer of integrated circuit (IC) solutions for the wireless communications market, today announced the selection of Jazz Semiconductor as its foundry partner for its ML1900 Personal Handyphone System (PHS) Transceiver. Targeted at the growing China wireless market, Micro Linear believes the ML1900 is the most highly integrated PHS transceiver available. Operating in the 1.9GHz PHS band, the ML1900 utilizes the Jazz 0.35µm silicon germanium (SiGe) BiCMOS platform (SBC35) to integrate the receiver, transmitter, synthesizer and power amplifier functions in a single chip solution and is available in production volumes.

The Jazz SBC35 platform supports the feature set that allowed Micro Linear to integrate various functions including receive and transmit chains as well as the synthesizer and the power amplifier. Using the 0.35µm SiGe BiCMOS, Micro Linear was able to perform low cost CMOS integration with high-Q inductors and high-density capacitors for compact layouts, to optimize die size and cost. Overall development time was greatly reduced as Jazz device models accurately predicted high frequency circuit performance.

Micro Linear's entry into China's emerging PHS market comes at a time when the country is rapidly deploying and adopting new wireless standards for communication. There are currently over 60 million PHS subscribers, over 25 million of which were added in 2004 alone. The PHS system realized early success in the Japan market as a local wireless communication standard that can be deployed quickly and rapidly at a lower cost than GSM or emerging 3G standards.

According to Morry Marshall, VP of strategic technologies, Semico Research Group, "An integrated solution for the cell phone front end, combining the power amplifier, synthesizer, and send and receive functions, is undoubtedly an optimum solution, saving cost and minimizing size. The Micro Linear ML1900 has achieved that, using the Jazz Semiconductor foundry and SiGe BiCMOS process to provide an integrated PHS transceiver, an excellent solution to address the rapidly growing Chinese market."

"We are expanding our market with the introduction of our ML1900 PHS product and we believe a reliable foundry partner is key to our success in this segment," said Brent Dix, VP of engineering at Micro Linear. "We are poised to achieve our desired results as Jazz has proven to be an excellent partner in our previous relationship for the ML5800, the industry's first 5.8GHz single-chip FSK transceiver."

"With our SBC35 offering, we allow aggressive companies such as Micro Linear to take advantage of a modular, low cost, proven process platform to meet their time-to-market needs quickly and cost effectively," said Paul Kempf, chief technology and marketing officer for Jazz Semiconductor. "We believe that collaborative partnerships between a foundry and its customers are key to the timely, efficient launch of complex, innovative products. We look forward to an ongoing, successful partnership with Micro Linear."
