HMC256 Sub-Harmonic I/Q Mixer Chip, 5.9 - 12 GHz
The HMC256 chip is a compact, 2.08 mm², I/Q Mixer MMIC which can be used as an Image Reject Mixer (IRM) or Single Side Band (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.
