HMC339_09

HMC339 v02.1007 GaAs MMIC SUB-HARMONICALLY PUMPED MIXER, 33 - 42 GHz Typical Applications The HMC339 is ideal for: • 33 to 42 GHz Microwave Radios Features Integrated LO Amplifier: +2 dBm Input Sub-Harmonically Pumped (x2) LO High 2LO/RF Isolation: > 37 dB Die Size: 1.32 x 0.81 x 0.1 mm 3 MIXERS - SUB-HARMONIC - CHIP • Up and Down Converter for Point to Point Radios • Satellite Communication Systems Functional Diagram General Description The HMC339 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 1.07mm2. 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 +2 dBm nominal drive requirement. All data is measured with the chip in a 50 ohm test fixture connected via 0.025mm (3 mil) ribbon bonds of minimal length
