Functional Schematic
Description and Applications:
The FMS2003QFN is a low loss, high power and linear single pole four throw Gallium Arsenide
antenna switch designed for use in mobile handset applications. The die is fabricated using the
Filtronic FL05 0.5
m switch process technology, which offers excellent performance optimised for
switch applications. The FMS2003QFN 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.
