HMC128G8_06

HMC128G8 v02.1105 GaAs MMIC SMT DOUBLEBALANCED MIXER, 1.8 - 5 GHz Typical Applications The HMC128G8 is ideal for: • Base Station Features Conversion Loss: 10 dB LO to RF and IF Isolation: >30 dB High Third-Order Intercept: +18 dB 7 MIXERS - SMT • MMDS • WirelessLAN • Wireless Local Loop Functional Diagram General Description The HMC128G8 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.

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.
