Wideband IF: DC to 1.5 GHz
Small Size: 1.3 mm x 1.6 mm
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.

Image Reject Mixer Suggested Application Circuit
Below in Figure 1 is a photo and in Figure 2 a schematic of the HMC256 image reject mixer MMIC die connected to a quadrature
hybrid (120 MHz) manufactured by Merrimac Industries West Caldwell, NJ (P/N QHZ-2A-120).
Data presented for the HMC256 MMIC IRM was obtained using the circuit described here. Please note that the image rejection
and isolation performance is dependent on the selection of the low frequency hybrid. The performance specification of the low
frequency quadrature hybrid as well as the phase balance and VSWR of the interface circuit to the HMC256 MMIC will effect the
overall IRM performance.
