Functional Diagram
General Description
The HMC-C046 is a passive I/Q MMIC mixer housed
in a miniature hermetic module which can be used as
either an Image Reject Mixer (IRM) 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 Upper Side Band (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.

Interface Schematic
This pin is DC coupled. For applications not requiring operation to DC, this port should be DC blocked
externally using a series capacitor whose value has
been chosen to pass the necessary IF frequency
range. For operation to DC, this pin must not source/
sink more than 3mA of current or part non-function
and possible part failure will result.
This pin is DC coupled
and matched to 50 Ohms.
