Functional Diagram
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.
