HMC338 v03.1007 GaAs MMIC SUB-HARMONICALLY PUMPED MIXER, 26 - 33 GHz Typical Applications Features The HMC338 is ideal for: Integrated LO Ampl ifier: -5 dBm Input General Purpose Applications Sub-Harmonically Pumped (x2) LO 26 and 33 GHz Microwave Radios High 2LO/RF Isolation: 33 dB 3 Up and Down Converter for Die Size: 1.32 x 0.97 x 0.1 mm Point-to-Point Radios Satellite Communication Systems Functional Diagram General Description The HMC338 chip is a general purpose sub-harmoni- cally pumped (x2) MMIC mixer with an integrated LO ampl ifier which can be used as an upconverter or downconverter in the 26 to 33 GHz frequency range. The chip utilizes a GaAs PHEMT technology that 2 results in a small overall chip area of 1.28mm . 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 -5 dBm nominal drive requirement. All data is measured with the chip in a 50 ohm test fi xture connected via 0.076 mm (3 mil) ribbon bonds of minimal length <0.31 mm (<12 mils).
