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 downconverter. The chip utilizes a GaAs PHEMT technology
that results in a small overall chip area of 1.28mm2.
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 measured with the chip in a 50 ohm test fixture connected
via 0.025 mm (1 mil) diameter wire bonds of minimal
length
