Description and Applications:
The FMS2014QFN is a low loss, high power and linear single pole double 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 excellent performance optimised for
switch applications. The FMS2014QFN is designed for use in dual/tri and quad band GSM handset
antenna switch modules and RF front-end modules. It can also find use in other applications where
high power and linear RF switching is necessary.
Electrical Specifications: (T_AMBIENT = 25°C,V_ctrl = 0V/2.5V, Z_IN = Z_OUT = 50Ω)
