High power Tx/Rx switches target LTE, TD-SCDMA, WiMAX and military radio

May 30, 2012 // By Jean-Pierre Joosting
Richardson RFPD has announced the availability and full design support capabilities for two high power Tx/Rx switches from M/A-COM Technology Solutions (M/A-COM Tech). Both devices are well-suited for high power LTE, TD-SCDMA, WiMAX, and military radio applications, and are offered in compact, surface mount 4-mm PQFN packages.

The MASW-000932 is an SPDT high power, broadband, high linearity, common anode, PIN diode Tx/Rx switch for applications from 10 MHz to 4.0 GHz. This broadband switch is ideal for use in WiMAX and WiFi customer premises equipment (CPE), as well as software defined radio (SDR), picocell and femotcell Tx/Rx switching applications. The device incorporates a PIN diode die fabricated with M/A-COM Tech’s patented Silicon-Glass HMIC process. The process also provides full top side polymer passivation to ensure robust performance with excellent Isolation to loss ratio on both the transmit and receive states.

This switch provides 80.0-W of CW power handling with 72 dBm IIP3 at 2010 MHz for outstanding switch performance. Additional key features include: low insertion loss: Tx of 0.25 dB at 2010 MHz; and high isolation: Rx of 43 dB at 2010 MHz

The MASW-000936 is an SPDT high power, broadband, high linearity, PIN diode Tx/Rx switch for applications from 50 MHz to 6.0 GHz, including WiMAX and WiFi. This device incorporates PIN diode die fabricated with M/A-COM Tech's low loss, high isolation switching diode process. It handles up to 120-W CW at 2.7 GHz at 85 °C. Additional features include: low insertion loss: Tx of 0.20 dB at 2.7 GHz; and high isolation: Rx of 51 dB at 2.7 GHz.
