HMC264

MIXERS - SUB-HARMONIC - CHIP v02.1007 Typical Applications The HMC264 is ideal for: Microwave Point-to-Point Radios 3 LMDS SATCOM Functional Diagram HMC264 GaAs MMIC SUB-HARMONICALLY PUMPED MIXER, 20 - 32 GHz Features Integrated LO Amplifier: -4 dBm Input Sub-Harmonically Pumped (x2) LO High 2LO/RF Isolation: 40 dB Small Size: 1.32 x 0.97 x 0.1 mm General Description The HMC264 chip is a sub-harmonically pumped (x2) MMIC mixer with an integrated LO amplifier which can be used as an upconverter or downconverter. The chip utilizes a GaAs PHEMT technology that results in a small overall chip area of 1.28mm2. The 2LO to RF isolation is excellent eliminating the need for additional filtering. The LO amplifier is a single bias (+3V to +4V) two stage design with only -4 dBm nominal drive requirement. All data is measured with the chip in a 50 ohm test fixture connected via 0.025 mm (1 mil) diameter wire bonds of minimal length <0.31 mm (<12 mils).
