Functional Diagram
General Description
The HMC620LC4 is a compact I/Q MMIC mixer in a
leadless“Pbfree”RoHScompliantSMTpackage,which
can be used as either an Image Reject Mixer (IRM) 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 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 compatible with high volume surface mount
manufacturing techniques.
