HMC-C046
GaAs MMIC I/Q MIXER MODULE
20 - 31 GHz
v02.0711
General Description
Features
Typical Applications
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 Side-
band 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 consis-
tent 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.
Functional Diagram

Pin Number Function Description Interface Schematic
1 RF This pin is AC coupled and
matched to 50 Ohms.
2 IF2
This pin is DC coupled. For applications not requir-
ing 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.
