General Description
Functional Diagram
The HMC-MDB218 is a sub-harmonically pumped (x2)
MMIC 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
and the Shottky devices are fully passivated for reliable
operation. The HMC-MDB218 Sub Harmonic IRM 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.
