General Description

The HMC168C8 is a miniature double-bal­anced mixer in a non- hermetic ceramic
surface mount package that can be used as
an upconverter, downconverter or biphase
modulator. 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 and unit-to-unit consistency. This
mixer has applications in point-to-point mi­crowave radios and 5.8GHz ISM band cir­cuits where small size and surface mount
compatibility are important.
