General Description
The HMC555 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
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 12 mil length bond wires on each port. A low
frequency quadrature hybrid was used to produce
a 100 MHz USB IF output. This compact mixer is a
much more compact alternative to hybrid style Image
Reject Mixers and Single Sideband Upconverter
assemblies, and is ideal for microwave radio
applications. The redundant IF port connections
located on opposing sides of the HMC555 chip,
provide added layout flexibility.
