General Description
Functional Diagram
The HMC-MDB277 is a passive Double Balanced
MMIC Mixer which utilizes GaAs Heterojunction
Bipolar Transistor (HBT) Shottky diode technology
and can be used as either an upconverter or a
downconverter. All bond pads and the die backside
are Ti/Au metallized and the Shottky devices are
fully passivated for reliable operation. The HMCMDB277 Double Balanced 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. This compact MMIC is a much smaller
and more consistent alternative to hybrid style
double balanced mixer assemblies. All data shown
herein is measured with the chip in a 50 Ohm
environment and contacted with RF probes.
