General Description
The HMC339 chip is a sub-harmonically pumped (x2) MMIC mixer with an integrated LO amplifi er 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 fi ltering. The LO amplifi er 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 fi xture connected via 0.025mm (3 mil) ribbon bonds of minimal length <0.31 mm (<12 mils).

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

Typical Applications
The HMC339 is ideal for:
• 33 to 42 GHz Microwave Radios
• Up and Down Converter for Point to Point Radios
• Satellite Communication Systems
