22 GHz to 32 GHz, GaAs, MMIC, I/Q Mixer

The HMC524ALC3B is a compact gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), in phase quadrature (I/Q) mixer in a leadless RoHS compliant surface-mount (SMT) ceramic package. This device can be used as either an image reject mixer or a single-sideband upconverter. The mixer uses two standard, double balanced mixer cells and a 90° hybrid coupler fabricated in a GaAs, metal–semiconductor field effect transistor (MESFET) process. A low frequency quadrature hybrid produces a 100 MHz IF output.

This device is a much smaller alternative to hybrid style image reject mixers and single-sideband upconverter assemblies. The HMC524ALC3B eliminates the need for wire bonding, allowing use of surface-mount manufacturing techniques.
