Functional Diagram
General Description
The HMC556 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 pro-
duce a 100 MHz USB IF output. This compact mixer
is a much smaller 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 HMC556 chip,
provide added layout flexibility.
