The HMC525LC4 is a compact I/Q MMIC mixer in a
leadless “Pb free” 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 HMC525LC4 eliminates the need
for wire bonding allowing use of surface mount
manufacturing techniques.
