The FMS2007QFN is a low loss linear Double-Pole Double-Throw dual band diversity switch
designed for use in WLAN applications. The die is fabricated using the Filtronic FL05 0.5µm switch
process technology, which offers leading edge performance optimised for switch applications. Typical
applications are for UNII, Hiperlan, 802.11a and 802.11b/g systems that employ two antennas for
transmit and receive diversity.
