HMC128G8
GaAs MMIC SMT DOUBLE-
BALANCED MIXER, 1.8 - 5 GHz
Features
Conversion Loss: 10 dB
LO to RF and IF Isolation: >30 dB
High Third-Order Intercept: +18 dB
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 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 balance in the circuit resulting in high LO/RF and
LO/IF isolations.
