GENERAL DESCRIPTION
The HMC521ALC4 is a compact, gallium arsenide (GaAs),
monolithic microwave integrated circuit (MMIC), inphase
quadrature (I/Q) mixer in a RoHS compliant, 24-terminal
ceramic leadless chip carrier (LCC) 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 intermediate
frequency (IF) output. This device is a smaller alternative to
hybrid style image reject mixers and single sideband upconverter
assemblies. The HMC521ALC4 eliminates the need for wire
bonding, allowing use of surface-mount manufacturing
techniques.
