General Description
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 P0.1dB
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.
