HMC342LC4

GaAs PHEMT MMIC LOW NOISE

AMPLIFIER, 13 - 25 GHz

Features

Noise Figure: 3.5 dB

Gain: 22 dB

Single Positive Supply: +3V @ 43 mA

50 Ohm Matched Input/Output

RoHS Compliant 4x4 mm SMT Package

General Description

The HMC342LC4 is a GaAs pHEMT MMIC Low

Noise Amplifier housed in a leadless 4x4 mm RoHS

compliant SMT package. Operating from 13 to 25

GHz, the amplifier provides 22 dB of gain and +19

dBm of output IP3 from a single +3V supply. The

low noise figure performance of 3.5 dB is ideal for

receive and transmit pre-driver applications. The RF

I/Os are DC blocked and matched to 50 Ohms for

ease of use. The HMC342LC4 allows the use of

surface mount manufacturing techniques and requires

no external matching components.

Electrical Specifications, TA = +25° C, Vdd = +3V, Idd = 43 mA
