Functional Diagram
General Description
The HMC522LC4 is a compact I/Q MMIC mixer in a
leadless “Pb free” 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 freq-
uency 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
HMC522LC4 eliminates the need for wire bonding
allowing use of surface mount manufacturing
techniques.
