Functional Diagram
General Description
The HMC264 chip is a sub-harmonically pumped
(x2) MMIC mixer with an integrated LO amplifier
which can be used as an upconverter or down-
converter. The chip utilizes a GaAs PHEMT tech-
nology that results in a small overall chip area
of 1.28mm
2
. 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 -4dBm nominal drive
requirement. All data is measured with the chip in
a 50 ohm test fixture connected via 0.025 mm (1
mil) diameter wire bonds of minimal length <0.31
mm (<12 mils).
