GaAs MMIC LOW NOISE
AMPLIFIER, 3.5 - 7.0 GHz
v03.0409
General Description
Features
Functional Diagram
The HMC392LC4 is a GaAs MMIC Low Noise Ampli er
which operates between 3.5 and 7.0 GHz. Housed
in a leadless 4x4 mm SMT package, this ampli er
provides 16 dB of gain, 2.5 dB noise  gure and 30
dBm IP3 from a +5V supply voltage. HMC392LC4
functions well as a low noise front end or as a driver
ampli er. The RF I/Os are DC blocked and matched to
50 Ohms for ease of use. The HMC392LC4 allows the
use of surface mount manufacturing techniques and
is suitable for high reliability military, industrial and
space applications.

[1] Reference this number when ordering complete evlaution PCB
[2] Circuit Board Material: Rogers 4350.
List of Materials for Evaluation PCB 117490 [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.
