| HMC170C8 v02.1105 GaAs MMIC SMT DOUBLEBALANCED MIXER, 2.5 - 4 GHz Features Conversion Loss: 9.0 dB LO to RF Isolation: 45 dB Surface Mount Small Size, No DC Bias Required Typical Applications The HMC170C8 is ideal for: * Microwave Point-to-Point 7 MIXERS - SMT * RADAR * VSAT Functional Diagram General Description The HMC170C8 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 where small size and surface mount compatibility are important.
