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.
