HMC461LP3

InGaP HBT 1 Watt High IP3

AMPLIFIER, 1.7 - 2.2 GHz

v01.0604

General Description

Features

Functional Diagram

The HMC461LP3 is a 1.7 - 2.2 GHz high

output IP3 GaAs InGaP Heterojunction Bipolar

Transistor (HBT) dual-channel MMIC amplifier.

The linear performance of two HMC455LP3

high IP3 drivers is offered in this single IC which

can be configured in a balanced or push-pull

amplifier circuit. The amplifier provides 12 dB of

gain and +30.5 dBm of saturated power at 48%

PAE from a single +5 Vdc supply while utilizing

external baluns in a balanced configuration.

The high output IP3 of +45 dBm coupled with

the low VSWR of 1.2:1 makes the HMC461LP3

an ideal driver amplifier for PCS/3G wireless

infrastructure. A low cost, leadless 3x3 mm QFN

surface mount package (LP3) houses the dual

MMIC amplifier IC. The LP3 provides an exposed

base for excellent RF and thermal performance.
