GaAs MMIC 20 Watt Failsafe Switch 0.2 to 2.2 GHz

The HMC546MS8G(E) is a low-cost SPDT switch in 8-lead MSOP8G surface mount package for use in transmit-receive applications which require very low distortion at high signal power levels, up to 10 watts. The device can control signals from 200 - 2200 MHz* and is especially suited for cellular booster, PMR and automotive telematic applications. The design provides exceptional P0.1 dB of +40 dBm and +65 dBm IIP3 on the Transmit (Tx) port. The failsafe topology allows the switch to provide a low loss path from RFC to Tx, when no DC power is available.
