General Description
The HMC527LC4 is a compact general purpose I/Q
MMIC mixer in a leadless RoHS compliant SMT pack-
age, 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 Upcon-
verter assemblies. The HMC527LC4 eliminates the
need for wire bonding allowing use of surface mount
manufacturing techniques.
