HMC446 / 446E

v03.0805

GaAs MMIC 10W T/R

SWITCH, 824 - 894 MHz*

Typical Applications

Features

The HMC446 / HMC446E is ideal for:

• ISM/Cellular Portables/Handsets

• Automotive Telematic Applications

• Mobile Radio

Low Insertion Loss: 0.6 dB

High IIP3: +65 dBm

High Input P0.1 dB: +40 dBm Tx

Positive Control: 0/+5V to 0/+8V

Ultra Small Package: SOT26

Functional Diagram

General Description

The HMC446 & HMC446E are low-cost SPDT swit-

ches in 6-lead SOT26 packages 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 824 - 894 MHz* and

is especially suited for cellular booster and auto-

motive telematic applications. The design provides

exceptional P0.1 dB of +40 dBm and +65 dBm IIP3

on the Transmit (Tx) port. The Tx port is a reﬂective

open when “Off” while the Rx port is a reﬂective short

when “Off”. On-chip circuitry allows single positive

supply operation at very low DC current with a single

control input (Vctl).
