GENERAL DESCRIPTION
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.
