HMC527
GaAs MMIC I/Q MIXER
8.5 - 13.5 GHz
v01.1007
General Description
FeaturesTypical Applications
The HMC527 is a compact I/Q MMIC mixer which can
be used as either an Image Reject Mixer 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 xture 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 USB IF output. This product is a much
smaller alternative to hybrid style Image Reject Mixers
and Single Sideband Upconverter assemblies.
