FMS2028 Datasheet, PDF (1/5 Pages) Filtronic Compound Semiconductors – SP6T GaAs Multi-Band GSM Antenna Switch

SP6T GaAs Multi-Band GSM Antenna Switch
FMS2028
Preliminary Datasheet v2.1
FEATURES:
• Available in die form
• Very low Tx Insertion loss
• High Tx-Rx isolation >45dB typ. at 1.8GHz
• High Tx-Tx isolation >30dB typ. at 1.8GHz
• Excellent low control voltage performance
• Excellent harmonic performance
GENERAL DESCRIPTION:
FMS2028 is a low loss, high power single
pole six throw Gallium Arsenide antenna
switch. The die is fabricated using the
Filtronic FL05 0.5µm switch process
technology that offers leading edge
performance optimised for switch
applications. FMS2028 is designed for use
in dual-, tri- and quad-band GSM handset
antenna switch and RF front-end modules.
