MA8334 Series High Power Multi-Throw PIN Diode Switch Modules V5 1 Features Absolute Maximum Ratings SPDT and SP3T Series Diode Designs Low Intermodulation Distortion, 80 dBc Parameter Absolute Maximum High Average Power, 100 W Reverse Voltage Voltage Rating per Diode Wide Bandwidth, 10 MHz to 1000 MHz Low Insertion Loss Forward Current + 250 mA per diode High Isolation RoHS Compliant Operating Temperature -65 C to +125 C Storage Temperature -65 C to +150 C Description and Applications Junction Temperature +175 C M/A-COM Technology Solutions MA8334 Series of multi-throw high power switch modules are 5 W + 25 C . Power Dissipation SPDT and SP3T devices intended for use from derated to 0 W + 125 C . 10 MHz to 1000 MHz. They are designed to func- 1. Operation of this device above any one of these parameters tion with an input power of 100 watts, CW, into a may cause permanent damage. 50 load with a nominal source VSWR of 1.3:1. These switch modules are constructed using ad- vanced 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 Techs, high voltage, CERMACHIP PIN diode chip distinguished by its low thermal resistance and low intermodulation distortion. Ap- MA MA 8334 plications for the MA8334 switch modules include 8334 -001 -004 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.
