P35-4229-000-200 Marconi Optical Components GaAs MMIC SPDT Reflective Switch, DC - 20GHz Features · · · · · Ultra Broadband Low insertion loss 2.0dB typ at 18GHz Fast switching speed High isolation 45dB at 10GHz Through GaAs Vias for improved performance Description The P35-4229-000-200 is a high performance Gallium Arsenide monolithic single pole double throw broadband 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 MOC's 0.5µm gate length MESFET process (S20) and is fully protected using Silicon Nitride passivation for excellent performance and reliability.
