General Description
The HMC-C044 is a passive I/Q MMIC mixer housed
in a miniature hermetic module which can be used as
either an Image Reject Mixer or a Single Sideband
Upconverter. The module utilizes two standard Hittite
double balanced mixer cells and a 90 degree hybrid
fabricated on a GaAs MESFET process. A low frequency quadrature hybrid was used to produce a 100
MHz USB IF output. This MMIC based module is a
more reliable and consistent alternative to hybrid style
I/Q Mixers and Single Sideband Converter assemblies. The module features removable SMA connectors which can be detached to allow direct connection
of the I/O pins to a microstrip or coplanar circuit.
