General Description
The HMC524LC3B 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
standard Hittite mixer cells and a 90 degree hybrid
fabricated in a GaAs MESFET process. 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. The
HMC524LC3B eliminates the need for wirebonding,
allowing the use of surface mount techniques.
