FMS2007QFN

DC-6GHz DPDT Diversity Switch

Features:

♦ 3x3x0.9mm Packaged pHEMT Switch

♦ Very High Tx-Rx isolation

♦ Suitable for WLAN 802.11a and 802.11b/g

Applications

♦ Filtronic Advanced GaAs pHEMT

Technology

♦ Low Insertion Loss

♦ Excellent low control voltage performance

Description and Applications:

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 0.5

µm 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.
