GENERAL DESCRIPTION
The HMC546LP2E is a failsafe SPDT switch in a leadless DFN
surface-mount plastic package for use in transmit/receive and
LNA protection applications that require very low distortion and
high power handling of up to 10 watts.
The HMC546LP2E requires external matching and is suitable
for narrow-band applications within 200 MHz to 2700 MHz.

This narrow-band switch is well suited for WiMAX and WiBro
repeaters, private mobile radio (PMR), and automotive
telematic applications. The design provides exceptional P0.1dB
of 40 dBm and IIP3 of 65 dBm 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.
