HMC129G8
GaAs MMIC SMT DOUBLE-
BALANCED MIXER, 4 - 8 GHz
v02.1105
General Description
Features
Functional Diagram
Conversion Loss: 8 dB
LO to RF and IF Isolation: 30 dB
Small Size, No DC Bias Required
Electrical Speci cations, TA = +25° C, LO Drive = +15 dBm
Typical Applications
The HMC129G8 is ideal for:
• UNII & HiperLAN
• Military & Space
• Test Equipment
The HMC129G8 is a miniature double-balanced mixer
in a hermetic surface mount package that can be used
as an upconverter or downconverter. The device is
a passive diode/balun type mixer with high dynamic
range. Noise gure is essentially equal to the conver-
sion loss. The mixer can handle larger signal levels
than most active mixers due to the high third order
intercept. MMIC implementation provides excep-
tional balance in the circuit resulting in high LO/RF
and LO/IF isolations.

Evaluation PCB
Item Description
J1 - J3 PCB Mount SMA RF Connector
U1 HMC129G8 Mixer
PCB [2] 104880 Evaluation Board
[1] Reference this number when ordering complete evaluation PCB
[2] Circuit Board Material: Rogers 4350
The circuit board used in the nal application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected 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
Hittite upon request.
