General Description
The HMC265 chip is a sub-harmonically pumped (x2)
MMIC downconverter with integrated LO & IF amplifi-
ers. The chip utilizes a GaAs PHEMT technology that
results in a small overall chip area of 1.74 mm². 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 -4 dBm
nominal drive requirement. All data is 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). This downconverter IC is an excellent, smaller,
and more reliable replacement to hybrid diode based
downconverter MMIC assemblies.
