Description and Applications:
The FMS2020QFN is a low loss, high power and linear 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 FMS2020QFN is designed for use in L, S, and C
band wireless applications and WLAN access points where high linearity switching is required.
Electrical Specifications: (T_AMBIENT = 25°C,V_ctrl = 0V/2.5V, Z_IN = Z_OUT = 50Ω)
