HMC451LC3

GaAs PHEMT MMIC MEDIUM

POWER AMPLIFIER, 5 - 20 GHz

v04.1208

General Description

Features

Functional Diagram

The HMC451LC3 is an efficient GaAs PHEMT

MMIC Medium Power Amplifier housed in a leadless

RoHS compliant SMT package. Operating between

5 and 20 GHz, the amplifier provides 19 dB of gain,

+21 dBm of saturated power and 21% PAE from a

single +5V supply. This 50 Ohm matched amplifier

does not require any external components and the

RF I/O’s are DC blocked, making it an ideal linear

gain block or driver for HMC SMT mixers. The

HMC451LC3

allows

the

use

of

surface

mount

manufacturing techniques.

Gain: 19 dB

Saturated Power: +21 dBm @ 21% PAE

Output IP3: +30 dBm

Single Supply: +5V @ 114 mA

50 Ohm Matched Input/Output

RoHS Compliant 3 x 3 mm SMT package

Typical Applications

The HMC451LC3 is ideal for use as a medium power

amplifier for:

• Microwave Radio & VSAT

• Military & Space

• Test Equipment & Sensors

• Fiber Optics

• LO Driver for HMC Mixers
