RF Micro Devices Inc. has begun shipping its RF3283CR, a GSM/GPRS transmit module designed for GSM900/DCS1800 2G handsets. The transmit module is specifically tailored to enhance the performance of SoC RF solutions, which incorporate the cellular transceiver with the handset baseband.

2G handsets represent the majority of volume in high-growth emerging markets and are increasingly developed using SoC RF solutions. The adoption of SoC solutions in 2G handsets favorably impacts the total addressable market and value proposition for RFMD (R, as the higher levels of functionality and systems-level knowledge in RFMD's cellular front ends, enhances SoC RF performance). RFMD is uniquely positioned to advance SoC RF performance and reduce the complexity of SoC-based handset implementation, given the company's industry leadership in cellular front ends, its deep cellular systems-level expertise and its proven experience supplying hundreds of millions of cellular transceivers to leading handset makers.

RF3283CR has a cellular power amplifier, a pHEMT antenna switch and harmonic filtering designed to lower voltage-controlled oscillator pulling and improve overall system performance. It also has RFMD's TRP-enhanced PowerStar integrated power control technology, which minimizes current variation by around 50 percent into non-ideal (3:1) loads, also known as "antenna mismatch," thus easing handset implementation for OEMs seeking improved total radiated power and specific absorption rate performance. Importantly, the RF3283CR delivers best-in-class harmonic emissions and insertion loss performance, which are critical front-end parameters when employed with SoC solutions.

RFMD's RF3283CR delivers pin-to-pin compatibility with its highly successful, high-volume predecessor, easing implementation and accelerating time-to-market of 2G handsets for leading handset development teams.
