HMC546LP2 / 546LP2E
v03.0809
GaAs MMIC 10W FAILSAFE SWITCH
0.2 - 2.7 GHz
Typical Applications
Features
The HMC546LP2 / HMC546LP2E is ideal for:
• LNA Protection, WiMAX & WiBro
High Input P0.1dB: +40 dBm Tx
Low Insertion Loss: 0.4 dB
• Cellular/PCS/3G & TD-SCDMA Infrastructure
• Private Mobile Radio & Public Safety Handsets
• Automotive Telematics
High Input IP3: +67 dBm
Positive Control: 0/+3V to 0/+8V
Failsafe Operation - Tx “On” When Unpowered
General Description
Functional Diagram
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 P0.1dB
of +40 dBm and +65 dBm IIP3 on the Transmit (Tx)
port. The failsafe topology allows the switch to pro-
vide a low loss path from RFC to Tx, when no DC
power is available.
