P35-4234-000-200 GaAs MMIC SP4T REFLECTIVE SWITCH, DC - 20GHz Features • Ultra Broadband • Low insertion loss 3.0dB typ at 18GHz • • Fast switching speed High isolation 38dB at 18GHz • Through GaAs Vias for improved performance 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.
