Description and Applications:
The FMS2018 is a low loss, high power and linear single pole seven throw Gallium Arsenide antenna
switch designed for use in mobile handset applications. The die is fabricated using the Filtronic FL05
0.5µm switch process technology which offers leading edge performance optimised for switch
applications. The FMS2018 is designed for use in dual/tri and quad-band GSM handset antenna
switch modules and RF front-end modules.
