GENERAL DESCRIPTION:
The FMS2029 is a low loss high isolation
broadband single-pole-single-throw Gallium
Arsenide switch, designed on the FL05 0.5µm
switch process from Filtronic. It offers
absorptive properties from both ports (50
Ohms terminations).
This process technology offers leading-edge
performance optimised for switch applications.
The FMS2029 is developed for the broadband
