General Description
The HMC265 chip is a sub-harmonically pumped
(x2) MMIC downconverter with integrated LO & IF
amplifiers. The chip utilizes a GaAs PHEMT tech-
nology 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.
