FMS2011

SP6T GaAs Multi-Band GSM Antenna Switch

Features:

♦ Available in die form

♦ Suitable for multi-band GSM/DCS/PCS/EDGE

applications

♦ Excellent low control voltage performance

♦ Excellent harmonic performance under

GSM/DCS/PCS power levels

♦ Very high Tx-Rx isolation >45dB typ. at 1.8GHz

♦ Very high Tx-Tx isolation >30dB typ. at 1.8GHz

♦ Very low Tx Insertion loss

♦ Very low control current

Description and Applications:

The FMS2011 is a low loss, high power and linear single pole six throw Gallium Arsenide antenna

switch designed for use in mobile handset applications. The die is fabricated using the Filtronic FL05

0.5

µm switch process technology which offers leading edge performance optimised for switch

applications. The FMS2011 is designed for use in dual, tri and quad – band GSM handset antenna

switch modules and RF front-end modules.
