Abstract :
A dual-mode RF front-end module is designed and implemented for Wi-Fi/WiMAX applications. It consists of a front-end MMIC and a dual-band power amplifier MMIC, both fabricated by 0.5 mum E/D-mode p-HEMT process. The front-end MMIC integrates a single-pole triple-throw antenna switch, two low noise amplifiers, a low pass filter and a diplexer in single chip. Overall module size is compact 7 mm times 10 mm, well tested with Wi-Fi/WiMAX OFDM signals.
