Functional Diagram
General Description
The HMC128G8 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 figure 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
balance in the circuit resulting in high LO/RF and LO/
IF isolations.
Electrical Specifi cations, TA = +25° C, LO Drive = +15 dBm

The circuit board used in the final 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
Hittite upon request.
