HMC129LC4
v03.0414
GaAs MMIC DOUBLE-BALANCED
MIXER, 4 - 8 GHz
General Description
Features
Functional Diagram
The HMC129LC4 is a general purpose double-
balanced MMIC mixer housed in a leadless “PB
Free” RoHS-Compliant SMT package which can
be used as an upconverter or downconverter in the
4 to 8 GHz band. The HMC129LC4 is ideally suited
for applications where small size, no DC bias, and
consistent IC performance are required. This mixer
can operate over a wide LO drive input of +9 to +15
dBm. It performs equally well as a Bi-Phase modulator
or demodulator. The HMC129LC4 eliminates the
need for wire bonding, allowing use of surface mount
manufacturing techniques.
Conversion Loss: 7 dB
LO to RF and IF Isolation: 40 dB
Input IP3: +17 dBm
RoHS Compliant 4x4 mm SMT Package
Typical Applications
The HMC129LC4 is ideal for:
• Microwave & VSAT Radios
• Test Equipment
• Military EW, ECM, C3I

Evaluation PCB
The circuit board used in the 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 circuit board shown is available from Hit-
tite upon request.
