Functional Diagram
General Description
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.
