General Description
The HMC620 is a compact I/Q MMIC mixer which can
be used as either an Image Reject Mixer (IRM) or a
Single Sideband Upconverter. The chip utilizes two
standard Hittite double balanced mixer cells and a 90
degree hybrid fabricated in a GaAs MESFET process.
All data shown below is taken with the chip mounted
in a 50 Ohm test fixture and includes the effects of
1 mil diameter x 20 mil length bond wires on each
port. A low frequency quadrature hybrid was used to
produce a 100 MHz upper side band (USB) IF output.
This product is a much smaller and more consistent
alternative to hybrid style Image Reject Mixers and
Single Sideband Upconverter assemblies.
