富威集團積極推廣 Peregrine的SP4T Switch產品應用方案

 2009-05-20

富威集團所代理的Peregrine為一高效能的RF CMOS 及混合訊號通訊IC的領導者,自有的專利技術UltraCMOS所製造出的產品具備了良好的線性度、隔離度、低插入損失及ESD的保護能力相當適合運用在無線設備、行動裝置、寬頻通訊、太空、國防及航天等領域。

UltraCMOS,是一Silicon-on -insulator(SOI)的技術,將很薄的矽置放在藍寶石的絕緣體上除了將結構簡單化之外,更提供的絕佳的產品特性。另外,Peregrine亦提供其他產品如:DSA(Digital signal attenuator), PLL(Phase Lock Loop), Prescaler及Mixer。

Peregrine的SP4T Switch 適用於WEDGE/CDMA的運用,其相關的應用如下:

Dual and Quad-Band GSM Application Examples
Dual-band GSM

Quad-band GSM with Dual-SAWs

CDMA and Antenna Tuning Application Examples
Multi-Mode, Multi-Band CDMA 2000

DVB-H Antenna Tuning
