HMC451LP3 / 451LP3E

GaAs PHEMT MMIC MEDIUM

POWER AMPLIFIER, 5 - 18 GHz

v00.0808

General Description

Features

Functional Diagram

The HmC451lp3(e) is an efficient GaAs pHemT

mmiC medium power Amplifier housed in a leadless

roHs compliant smT package. operating between

5 and 18 GHz, the amplifier provides 18 dB of gain,

+21 dBm of saturated power and 18% 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 lo driver for HmC mixers. The

HmC451lp3(e) eliminates the need for wire bonding,

and allows the use of surface mount manufacturing

techniques.

Gain: 18 dB

saturated power: +21 dBm @ 18% pAe

output ip3: +28 dBm

single supply: +5V @ 120 mA

50 ohm matched input/output

16 lead 3x3mm smT package: 9mm²

Typical Applications

The HmC451lp3(e) is ideal for:

• microwave radio & VsAT

• military & space

• Test equipment & sensors

• fiber optics

• lo Driver for HmC mixers
