General Description
The HMC256 chip is a compact, 2.08 mm2, I/Q
Mixer MMIC which can be used as an Image
Reject Mixer (IRM) or SSB upconverter. The
chip utilizes two standard Hittite double-balanced
mixer cells and a Lange Coupler realized in GaAs
MESFET technology. All data is with the chip in
a 50 Ohm test fixture connected via 0.025 mm (1
mil) diameter wire bonds of minimal length <0.51
mm (<20 mils). A low frequency quadrature hybrid
was used to interface the MMIC IF ports to a 120
MHz IF USB output. This provides an example of
the I/Q Mixer in an IRM application. The IF may
be used from DC to 1.5 GHz. This I/Q Mixer is
a more reliable, much smaller replacement to
hybrid drop-in style I/Q Mixer assemblies.
