HMC-C042
GaAs MMIC I/Q MIXER MODULE
8.5 - 13.5 GHz
v03.0310
General Description
Features
Typical Applications
The HMC-C042 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.

Pin Number Function Description Interface Schematic
1RF This pin is AC coupled
and matched to 50 Ohms.
2IF1
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 3 mA of current or part non-function
and possible part failure will result.

4LO This pin is AC coupled
and matched to 50 Ohms.
