Description
The P35-0702R is a high performance Gallium Arsenide monolithic single pole double throw RF switch suitable for use in
broadband communications and instrumentation applications. A short circuit termination is presented at the isolated
output of the switch. Control is effected by the application of complimentary 0V and -5V levels to the control lines in
accordance with the truth table below.
The die is fabricated using MOC's 0.5µm gate length MESFET process (S20) and is fully protected using Silicon Nitride
passivation for excellent performance and reliability.
