RF High Average Power Multi-Throw PIN Diode Switch Modules Features • • • • • • SPDT and SP3T Series Diode Designs Lower Intermodulation Distortion, 80 dBc Higher Average Power, 100 W Higher B.W., 10 MHz to 1000 MHz Lower Insertion Loss / Higher Isolation Lead-Free ( RoHS Compliant ) Available with 260 °C Reflow Compatibility Description and Applications M/A-COM’s MA8334 Series of Multi-Throw High Power Switch Modules are SPDT and SP3T Devices designed for usage from 10 MHz to 1000 MHz. They are rated to operate at 100 Watts CW RF power with Nominal 1.3:1 Source and Load VSWR in 50 Ω. These switch modules are constructed using Ceramic-Hybrid technology and utilize PIN diode chips optimized for lower loss and higher operating reliability. These Switch Modules employ M/A-COM’s High Voltage CERMACHIP PIN diodes for Lower Thermal Resistance and Lower Intermodulation Products.
