GENERAL DESCRIPTION

The HMC525ACHIPS is a compact gallium arsenide (GaAs),

monolithic microwave integrated circuit (MMIC), in phase and

quadrature (I/Q), RoHS compliant mixer. The 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 fabricated in a GaAs, metal

semiconductor field effect transistor (MESFET) process. The

HMC525ACHIPS is a much smaller alternative to a hybrid

style image reject mixer and a single sideband upconverter

assembly. The HMC525ACHIPS eliminates the need for wire

bonding, allowing the use of surface-mount manufacturing

techniques.
