General Description

The HMC523LC4 is a compact general purpose

I/Q MMIC mixer in a leadless RoHS compliant SMT

package, which can be used as either an Image

Reject Mixer or a Single Sideband Upconverter. The

mixer utilizes two standard Hittite double balanced

mixer cells and a 90 degree hybrid fabricated in a

GaAs MESFET process. A low frequency quadrature

hybrid was used to produce a 100 MHz USB IF output.

This product is a much smaller alternative to hybrid

style Image Reject Mixers and Single Sideband

Upconverter assemblies. The HMC523LC4 eliminates

the need for wire bonding allowing use of surface

mount manufacturing techniques.
