HMC256

v03.1007 HMC256 GaAs MMIC I/Q MIXER 5.9 - 12 GHz MIXERS - I/Q MIXERS / IRM - CHIP 3 3-2 Typical Applications Features The HMC256 is ideal for: High Image Rejection: >30 dB Microwave Radio & VSAT Input IP3: +18 dB Test Instrumentation Wideband IF: DC to 1.5 GHz Military Radios Radar & ECM Die Size: 1.6 x 1.3 x 0.1 mm Space OLETE Functional Diagram 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 Single Sideband (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.
