HMC342LC4
v04.0514
GaAs PHEMT MMIC LOW NOISE
AMPLIFIER, 13 - 25 GHz
General Description
Features
Functional Diagram
The HMC342LC4 is a GaAs pHEMT MMIC Low
Noise Amplier housed in a leadless 4x4 mm RoHS
compliant SMT package. Operating from 13 to 25
GHz, the amplier provides 22 dB of gain and +19
dBm of output IP3 from a single +3V supply. The
low noise gure 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.

[1] Reference this number when ordering complete evaluation PCB
[2] Circuit Board Material: Rogers 4350.
List of Materials for Evaluation PCB 110209 [1]
The circuit board used in this application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation board should be mounted to an appro-
priate heat sink. The evaluation circuit board shown
is available from Hittite upon request.
