Description
AI
The HMC338 chip is a general purpose sub-harmonically pumped (x2) MMIC mixer with an integrated LO amplifier 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 results in a small overall chip area of 1.28mm2. The 2 LO 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 -5 dBm nominal drive requirement. All data is measured with the chip in a 50 ohm test fixture connected via 0.076 mm (3 mil) ribbon bonds of minimal length <0.31 mm (<12 mils).APPLICATIONSGeneral Purpose Applications26 and 33 GHz Microwave RadiosUp and Down Converter for Point-to-Point RadiosSatellite Communication Systems
