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 fi xture connected via 0.025 mm (1 mil) diameter wire bonds of minimal length
