MMIC SP3T Reflective
Switch, DC - 20GHz
The P35-4233-000-200 is a high performance broadband
Gallium Arsenide monolithic single pole three
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 Bookham Technology's 0.5 m
gate length MESFET process (S20) and is fully
protected using Silicon Nitride passivation for excellent
performance and reliability.
Features
Ultra Broadband
Low insertion loss 2.2dB typ
at 18GHz
Fast switching speed
High isolation 55dB at 18GHz
Through GaAs Vias for improved
performance
