HMC265_08

HMC265 v02.1007 GaAs MMIC SUB-HARMONICALLY PUMPED DOWNCONVERTER, 20 - 32 GHz Typical Applications The HMC265 is ideal for: • Microwave Point-to-Point Radios Features Integrated LO Amplifier: -4 dBm Input Sub-Harmonically Pumped (x2) LO Integrated IF Amplifier: 3 dB Gain Small Size: 1.32 x 1.32 x 0.1 mm 3 MIXERS - SUB-HARMONIC - CHIP • LMDS • SATCOM Functional Diagram General Description The HMC265 chip is a sub-harmonically pumped (x2) MMIC downconverter with integrated LO & IF amplifiers. The chip utilizes a GaAs PHEMT technology that results in a small overall chip area of 1.74 mm2. 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 with the chip in a 50 ohm test fixture connected via 0.025 mm (1 mil) diameter wire bonds of minimal length
