v00.0506
GaAs MMIC 10W FAILSAFE SWITCH
0.2 - 2.7 GHz
Typical Applications
The HMC546LP2 / HMC546LP2E is ideal for:
• LNA Protection, WiMAX, WiBro
• Cellular/PCS/3G, TD-SCDMA Infrastructure
• Private Mobile Radio and Public Safety Handsets
Features
High Input P0.1 dB: +40 dBm Tx
Low Insertion Loss: 0.4 dB
High IIP3: +67 dBm
Positive Control: 0/+3V to 0/+8V
Failsafe Operation - Tx “On” When Unpowered

Functional Diagram
General Description
The HMC546LP2 & HMC546LP2E are failsafe
SPDT switches in leadless DFN surface mount
plastic packages for use in transmit-receive, and
LNA protection applications which require very low
distortion and high power handling of up to 10 watts. The
device can control signals from 200 - 2700 MHz* and
is especially suited for WiMAX and WiBro repeaters,
PMR and automotive telematic applications. The
design provides exceptional P0.1 dB 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.
