MMIC SP6T Reflective
Switch, DC - 22GHz
This P35-4236-000-200 engineering datasheet describes
a high performance broadband Gallium Arsenide monolithic
single pole six 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 0.5m
gate length MESFET process (S20) and is fully protected
using Silicon Nitride passivation for excellent performance
and reliability.
Features
Ultra Broadband
Low insertion loss <3dB typ
at 20GHz
Fast switching speed
High isolation 40dB at 20GHz
Through GaAs Vias for improved
performance
