GaAs MMIC T/R SWITCH,

DC - 4 GHz

v00.0206

General Description

Features

Functional Diagram

Very Low Insertion Loss: 0.2 dB @ 1.0 GHz

High Input P1dB: +39 dBm

High Input IP3: +55 dBm

Positive Control: 0/+3V to 0/+5V

Compact SOT26 SMT Package

Typical Applications

The HMC544 / HMC544E is ideal for:

• Cellular/PCS/3G Infrastructure

• Basestations & Repeaters

• WLAN, WiMAX and WiBro

• Microwave and Fixed Wireless Radios

The HMC544 & HMC544E are low cost SPDT swit-

ches in 6-lead SOT26 packages for use in transmit-

receive applications which require very low insertion

loss at medium power levels. These devices can

control signals from DC to 4.0 GHz and are especially

suited for 450, 900, 1900, 2300, and 2700 MHz

applications with <0.5 dB insertion loss. This GaAs

PHEMT

design

provides

exceptional

linearity

performance of +36 dBm 1dB compression point and

+55 dBm third order intercept at +3 volt bias. RF1

and RF2 are reflective opens when “Off”.

On-chip

circuitry allows positive control operation at very low

DC current.
