Features CONVERSION LOSS: 8.2 dB LO TO RF AND IF ISOLATION: > 33 dB SURFACE MOUNT SMALL SIZE, NO DC BIAS REQUIRED HMC168C8 GaAs MMIC SMT DOUBLE-BALANCED MIXER 4.5 - 8 GHz General Description The HMC168C8 is a miniature double-bal- anced 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 con- version loss. The mixer can handle larger signal levels than most active mixers due to the high third order intercept. MMIC imple- mentation 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 mi- crowave radios and 5.8GHz ISM band cir- cuits where small size and surface mount compatibility are important.
