ESCRIPTION
:
FMS2028 is a low loss, high power single
pole six throw Gallium Arsenide antenna
switch. The die is fabricated using the
Filtronic FL05 0.5µm switch process
technology that offers leading edge
performance
optimised
for
switch
applications. FMS2028 is designed for use
in dual-, tri- and quad-band GSM handset
antenna switch and RF front-end modules.
