General Description
Functional Diagram
The HMC-MDB171 is a monolithic I/Q Mixer which
can be used as either an image reject mixer (IRM) or
a single sideband upconverter. This passive MMIC
mixer is fabricated with GaAs Heterojunction Bipolar
Transistor (HBT) Shottky diode technology. For
downconversion applications, an external quadrature
hybrid can be used to select the desired sideband
while rejecting image signals. All bond pads and the
die backside are Ti/Au metallized. The HMC-MDB171
I/Q MMIC Mixer is compatible with conventional die
attach methods, as well as thermocompression and
thermosonic wire bonding, making it ideal for MCM and
hybrid microcircuit applications. All data shown herein
is measured with the chip in a 50 Ohm environment
and contacted with RF probes.
