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 downcon-
verter. The device is a passive diode/balun type
mixer with high dynamic range. Noise fi gure is
essentially equal to the conversion loss. The
mixer can handle larger signal levels than most
active mixers due to the high third order intercept.
MMIC implementation provides exceptional bal-
ance in the circuit resulting in high LO/RF and
LO/IF isolations.

* Circuit Board Material: Rogers 4350
The circuit board used in the fi 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 connected
directly to the ground plane similar to that shown. A
suffi cient number of VIA holes should be used to con-
nect the top and bottom ground planes. The evalua-
tion circuit board shown is available from Hittite upon
request.
