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 <0.31 mm (<12 mils)
