HMC265 v02.1007 GaAs MMIC SUB-HARMONICALLY PUMPED DOWNCONVERTER, 20 - 32 GHz Typical Applications Features The HMC265 is ideal for: Integrated LO Ampl ifier: -4 dBm Input Microwave Point-to-Point Radios Sub-Harmonically Pumped (x2) LO LMDS Integrated IF Ampl ifier: 3 dB Gain 3 SATCOM Small Size: 1.32 x 1.32 x 0.1 mm Functional Diagram General Description The HMC265 chip is a sub-harmonically pumped (x2) MMIC downconverter with integrated LO & IF ampl ifi- ers. The chip utilizes a GaAs PHEMT technology that 2 results in a small overall chip area of 1.74 mm . The 2LO to RF isolation is excellent eliminating the need for additional fi ltering. The LO ampl ifier 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 fi xture connected via 0.025 mm (1 mil) diameter wire bonds of minimal length <0.31 mm (<12 mils). This downconverter IC is an excellent, smaller, and more reliable replacement to hybrid diode based downconverter MMIC assemblies.
