Functional Schematic
Description and Applications:
The FMS2031-001 is a 10 Watt, low loss, and single pole dual throw Gallium Arsenide antenna switch. The
die is fabricated using the Filtronic FL05 0.5µm switch process technology, which offers leading edge
performance optimised for switch applications. The FMS2031-001 is designed for use in WiMax, L, S, and C
band wireless applications and WLAN access points where high linearity switching is required.
