The FMS2027 is a low loss, high isolation broadband single-pole double-throw Gal-
lium Arsenide switch, designed on the FL05 0.5m switch process from RFMD. It
offers absorptive properties from the output (50 termination). This process tech-
nology offers leading-edge performance optimized for switch applications.
The FMS2027 is developed for the broadband communications, instrumentation,
and electronic warfare markets.
