HMC546MS8G / 546MS8GE
v02.0805
GaAs MMIC 10W T/R SWITCH
0.2 - 2.2 GHz
Typical Applications
Features
The HMC546MS8G / HMC546MS8GE is ideal for:
• Cellular/PCS/3G Infrastructure
High Input P0.1 dB: +40 dBm Tx
Low Insertion Loss: 0.4 dB
High IIP3: +65 dBm
• Private Mobile Radio and Public Safety Handsets
• Automotive Telematics
Positive Control: 0/+3V to 0/+8V
General Description
Functional Diagram
The HMC546MS8G & HMC546MS8GE are low-cost
SPDT switches in 8-lead MSOP8G surface mount
packagesforuseintransmit-receiveapplicationswhich
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. On-chip
circuitry allows single positive supply operation at very
low DC current with a single control input.
