v06.0809 GaAs MMIC 20W FAILSAFE SWITCH
0.2 - 2.2 GHz
General Description
Features
Functional Diagram
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
Electrical Speci cations, TA = +25° C, Vdd = 3V, Vctl = 0/+3 Vdc, 50 Ohm System*
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
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.

for values.
[2] Circuit Board Material: Rogers 4350
[3] When requesting an evaluation board, please reference
the appropriate evaluation PCB number listed in the table
“Components for Selected Frequencies.”
The circuit board used in the application should be
generated with proper RF circuit design techniques.
Signal lines at the RF port should have 50 Ohm
impedance and the package ground leads and
exposed paddle should be connected directly to
the ground plane similar to that shown above. The
evaluation circuit board shown above is available
from Hittite Microwave Corporation upon request.
