General Description
The HMC620LC4 is a compact I/Q MMIC mixer in
a leadless “Pb free” RoHS compliant SMT pack-
age, which can be used as either an Image Reject
Mixer (IRM) or a Single Sideband Upconverter.
The mixer utilizes two standard Hittite double bal-
anced mixer cells and a 90 degree hybrid fabri-
cated in a GaAs MESFET process. A low frequency
quadrature hybrid was used to produce a 100 MHz
upper side band (USB) IF output. This product
is a much smaller and more consistent alternative to
hybrid style Image Reject Mixers and Single Sideband
Upconverter assemblies. The HMC620LC4 is com-
patible with high volume surface mount manufacturing
techniques.
