Sirenza Microdevices PowerMax(TM) Power Amplifier Used in LUXIM Corporation's New LIFI(TM) Projection HDTV Light Source.

BROOMFIELD, Colo. -- Sirenza Microdevices (NASDAQ:SMDI) announced today that LUXIM Corporation's recently introduced revolutionary, long-life LIFI[TM] light source, as demonstrated in a new generation of micro display projection HDTVs at the 2007 Consumer Electronics Show in Las Vegas, NV, is driven by Sirenza's PowerMax[TM] power amplifier module. The rugged PowerMax PA[TM] provides LIFI[TM] with 170 watts of RF output power and a power-added efficiency of nearly 70 percent.

"We are pleased to provide the RF power for such an exciting new product," stated Joe Johnson, Sirenza's chief technology officer. "We combined our proprietary LDMOS building blocks with our PowerMax PA[TM] platform to produce a high performance, custom product meeting LUXIM's stringent requirements at a competitive price."

"Our manufacturing expertise in the U.S., Germany and Asia allows us to bring products like the PowerMax PA[TM] to the competitive consumer marketplace," added Jeff Gudewicz, Sirenza's standard product business unit director. "Our long history of efficient manufacture of RF power modules in very high volumes to support the CATV end market is a perfect fit for this strategic product line."

"We are thrilled that LIFI[TM] will be the first to bring solid state reliability to a high volume production HDTV light source and Sirenza's PowerMax PA[TM] enabled us to meet our performance and time-to-market goals," stated Tony McGettigan, LUXIM CEO. "The PowerMax PA[TM] delivers LIFI[TM] efficient RF power that meets the reliability and price expectations of consumer applications."

Sirenza uses its proprietary XeMOS II laterally diffused metal oxide semiconductor (LDMOS) semiconductor process technology to produce the devices used in the PowerMax PA[TM]. This high-voltage process is well-suited to applications requiring extreme ruggedness and high levels of efficient power at competitive prices.
