General Description
The HMC337 chip is a sub-harmonically pumped (x2) MMIC mixer with an integrated LO amplifer 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 1.28mm2. The 2LO to RF isolation is excellent eliminating the need for additional f ltering. The LO amplif er is a single bias (+3V to +4V) two stage design with only -5 dBm nominal drive requirement. All data is mea sured with the chip in a 50 ohm test f xture connected via 0.076 mm (3 mil) ribbon bonds of minimal length <0.31 mm (<12 mils).
