MMIC SPST Switch
1 - 50GHz
This P35-5200-000-200 engineering datasheet describes
a high performance Gallium Arsenide monolithic single pole
single throw broadband RF switch optimised for 20-50GHz
operation. It is suitable for use in broadband
communications, instrumentation and electronic warfare
applications. Control is effected by the application of 0V and
-5V levels to the control line in accordance with the truth
table below.
The die is fabricated using Bookham Technology's 0.2m
gate length HEMT process and is fully protected using
Silicon Nitride passivation for excellent performance and
reliability.
Features
Broadband Switch
Low insertion loss <0.8dB
typically 1-50GHz
Isolation typically 40dB at 50GHz
