LONDON Japanese passives to power supplies giant MurataManufacturing Co. Ltd. (Tokyo, Japan) has selected CMOS poweramplifiers from Black Sand Technologies Inc. (Austin, Texas) foruse in RF front-end modules for 3G mobile phone handsets. Integrating the PA together with other RF front-end components intoa single module allows for better optimization of performance,battery current, size, and cost, said Black Sand. "Tier 1 cellular manufacturers are demanding increasing levels ofsophistication and integration throughout the handset, and RF is noexception," said .Norio Nakajima, vice president of the modulebusiness unit at Murata, in a statement issued by Black Sand. John Diehl, CEO of Black Sand, could not put a value of the designwin with Murata. "There's no exclusivity either way. But we'vechosen to work together as best-in-class partners," he said. "Thisagreement represents a major opportunity for both companies:industry estimates tell us that the market for RF front endcomponents is growing at a CAGR of around 15 percent, and willreach in excess of $5.5 billion by 2014." Diehl was referencing amarket research report from Needham and Co. Mobile device manufacturers have long sought a viable CMOSalternative to GaAs that will enable them to benefit from animproved supply chain, higher reliability, and lower cost. Diehl said that envelope-tracking (ET), the method of matching PAvoltage to the instantaneous power output required was somethingthat CMOS PAs enabled but that the market seemed to be applying itmore to 4G than to 3G communications. "CMOS does allow more smarts in the PA. Our BST35 family has anintegrated power detector that can be used to achieve 2-dB ofadditional power output on the output antenna," he said. "We arebringing that [ET] capability into a 4G context. We have noannouncement on 4G-optimized ET for now." Diehl concluded: "Collaborating with ET partners is part of thestrategy," but he declined to name partners.
