Two New High Power Tx/Rx Switches
Richardson RFPD announces immediate availability and full design support capabilities for two new high power Tx/Rx switches from M/A-COM Technology Solutions Inc. (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 4mm 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 Watts of CW power handling with 72 dBm IIP3 at 2010 MHz for outstanding switch performance.
Additional key features of the MASW-000932 include:
? Low Insertion Loss: TX = 0.25 dB @ 2010 MHz
? High Isolation: Rx = 43 dB @ 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 Watts CW at 2.7 GHz at 85 ºC.
Additional key features of the MASW-000936 include:
? Low Insertion Loss: TX = 0.20 dB @ 2.7 GHz
? High Isolation: Rx = 51 dB @ 2.7 GHz
