MICROWAVE CORPORATION HMC142C8 v02.0302 GaAs MMIC SMT DOUBLEBALANCED MIXER, 6 - 15 GHz Typical Applications Features The HMC142C8 is ideal for: Input IP3: 20 dBm • Microwave Pt to Pt Radios Conversion Loss: 8.5 dB • VSAT Ground Equipment LO to RF Isolation: 35 dB Functional Diagram General Description The HMC142C8 is a miniature double-balanced mixer in a non-hermetic ceramic 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. 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. MIXERS - SMT 12 Electrical Specifications, TA = +25° C, LO Drive = +15 dBm Parameter Min. Max.

Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of VIA holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.
