GENERAL DESCRIPTION
The HMC525ALC4 is a compact gallium arsenide (GaAs),
monolithic microwave integrated circuit (MMIC), in phase
quadrature (I/Q) mixer in a 24-terminal, RoHS compliant, ceramic
leadless chip carrier (LCC) package. The device can be used as
either an image reject mixer or a single sideband (SSB)
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
HMC525ALC4 is a much smaller alternative to a hybrid style
image reject mixer and a SSB upconverter assembly. The
HMC525ALC4 eliminates the need for wire bonding, allowing the
use of surface-mount manufacturing techniques.
