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 addi-
tional 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).
