GaAs MMIC 20W FAILSAFE SWITCH
0.2 - 2.2 GHz
Typical Applications
The HMC546MS8G(E) is ideal for:
• LNA Protection, WiMAX, WiBro
• Cellular/PCS/3G Infrastructure
• Private Mobile Radio and Public Safety Handsets
• Automotive Telematics
Features
High Input P0.1dB: +40 dBm Tx
Low Insertion Loss: 0.4 dB
High IIP3: +65 dBm
Positive Control: 0/+3V to 0/+8V
Failsafe Operation: Tx “on” When Unpowered
Functional Diagram
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.
