Typical Applications
The HMC141C8 is ideal for:
Microwave Pt to Pt Radios
VSAT Ground Equipment
The HMC141C8 is a miniature passive double-
balanced mixer in a non-hermetic ceramic sur-
face mount package that can be used as an
upconverter or downconverter. The device is a
passive diode/balun type mixer with high dynamic
range. The mixer can handle larger signal levels
than most active mixers due to the high third
order intercept of 20 dBm. MMIC implementation
provides exceptional balance in the circuit result-
ing in high LO/RF and LO/IF isolations and unit-
to-unit consistency. This mixer has applications
where small size and surface mount compatibility
are important.

* 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.
