Functional Diagram
General Description
The HMC266 chip is a broadband GaAs MMIC
sub-harmonically pumped (x2) balanced passive
mixer which can be used as an upconverter or
downconverter in a small overall chip area of 1.9
mm

. The 2LO to RF isolation is excellent elimi-
nating the need for additional 鏗乴tering. All data is
with the chip in a 50 ohm test 鏗亁ture connected
via 0.076 mm (3 mil) ribbon bonds of minimal
length <0.31 mm (<12 mils). These devices are
much smaller and more reliable than hybrid diode
mixer designs.
