HMC129G8 v01.0801 MICROWAVE CORPORATION GaAs MMIC SMT DOUBLEBALANCED MIXER, 4 - 8 GHz Typical Applications Features The HMC129G8 is ideal for: Conversion Loss: 8 dB • UNII & HiperLAN LO to RF and IF Isolation: 30 dB • Military & Space Small Size, No DC Bias Required • Test Equipment Functional Diagram The HMC129G8 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 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. 12 MIXERS - SMT General Description Electrical Specifications, TA = +25° C, LO Drive = +15 dBm Parameter Min.

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.
