InGaP HBT 1 Watt High IP3

AMPLIFIER, 1.7 - 2.2 GHz

v02.0705

General Description

Features

Functional Diagram

The HMC461LP3 & HMC461LP3E are 1.7 - 2.2 GHz

high output IP3 GaAs InGaP Heterojunction Bipolar

Transistor

(HBT)

dual-channel

MMIC

amplifiers.

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 make the HMC461LP3 &

HMC461LP3E ideal driver amplifiers for PCS/3G

wireless infrastructures. 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.
