HMC751LC4

SMT PHEMT LOW NOISE

AMPLIFIER, 17 - 27 GHz

v00.0409

General Description

Features

Functional Diagram

The HMC751LC4 is a high dynamic range GaAs

PHEMT MMIC Low Noise Amplifier (LNA) housed in

a leadless “Pb free” RoHS compliant SMT package.

The HMC751LC4 provides 25 dB of small signal

gain, 2.2 dB of noise figure and output IP3 of +25 dBm.

The P1dB output power of +13 dBm also enables the

LNA to function as a LO driver for balanced, I/Q or

image reject mixers. The HMC751LC4 allows the use

of surface mount manufacturing techniques.
