The PE42693 is a HaRPTM-enhanced SP9T RF Switch developed on the UltraCMOSTM process technology. It addresses the specific design needs of the Quad-Band GSM Handset Antenna Switch Module Market for use in GSM/ PCS/EDGE/DCS/WCDMA handsets. The switch is comprised of two transmit ports that can be used for GSM/PCS/EDGE, three transmit/receive ports (TRX1, TRX2 and TRX3) that can be used for either WCDMA or as receive ports, and four symmetric receive ports. An on-chip CMOS decode logic facilitates fourpin low voltage CMOS control. High ESD tolerance of 1500 V at all ports, no blocking capacitor requirements, and on-chip SAW filter over-voltage protection devices make this the ultimate in integration and ruggedness. Peregrine's HaRPTM technology enhancements deliver high linearity and exceptional harmonics performance. It is an innovative feature of the UltraCMOSTM process, providing performance superior to GaAs with the economy and integration of conventional CMOS.
