Description
The P35-4234-000-200 is a high performance broadband Gallium Arsenide monolithic single pole four
throw RF switch. It is suitable for use in broadband communications, instrumentation and electronic
warfare applications. 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 MCL's 0.5µm gate length MESFET process (S20) and is fully protected using
Silicon Nitride passivation for excellent performance and reliability.
