GaAs MMIC 10W FAILSAFE SWITCH

0.2 - 2.7 GHz

General Description

Features

Functional Diagram

High Input P0.1dB: +40 dBm Tx

Low Insertion Loss: 0.4 dB

High Input IP3: +67 dBm

Positive Control: 0/+3V to 0/+8V

Failsafe Operation - Tx “On” When Unpowered

Typical Applications

The HMC546LP2 / HMC546LP2E is ideal for:

• LNA Protection, WiMAX & WiBro

• Cellular/PCS/3G & TD-SCDMA Infrastructure

• Private Mobile Radio & Public Safety Handsets

• Automotive Telematics

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.
