HMC521LC4
v04.0514
GaAs MMIC I/Q MIXER
8.5 - 13.5 GHz
General Description
FeaturesTypical Applications
The HMC521LC4 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 HMC521LC4 eliminates the need for wire
bonding allowing use of surface mount manufacturing
techniques.
