MA8334 Series High Power Multi-Throw PIN Diode Switch Modules Features ♦ ♦ ♦ ♦ ♦ ♦ ♦ SPDT and SP3T Series Diode Designs Low Intermodulation Distortion, 80 dBc High Average Power, 100 W Wide Bandwidth, 10 MHz to 1000 MHz Low Insertion Loss High Isolation RoHS Compliant Description and Applications M/A-COM Technology Solutions MA8334 Series of multi-throw high power switch modules are SPDT and SP3T devices intended for use from 10 MHz to 1000 MHz. They are designed to function with an input power of 100 watts, CW, into a 50 Ω load with a nominal source VSWR of 1.3:1. These switch modules are constructed using advanced hybrid technology and utilize PIN diode chips that have been optimized for low loss and high reliability. These switch modules make use of M/A-COM Tech’s, high voltage, CERMACHIP™ PIN diode chip distinguished by its low thermal resistance and low intermodulation distortion. Applications for the MA8334 switch modules include 100W incident power T/R antenna and diversity switches. Typical bias conditions for nominal switch operation are +50mA @ +1V for the low loss condition and -100V @ 0 mA for isolation.
