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 conver-
sion 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.
