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.

Description
This pad is AC coupled
and matched to 50 Ohms.
This pad is AC coupled
and matched to 50 Ohms.
This pad is DC coupled. For applications not
requiring operation to DC, this port should be DC
blocked externally using a series capacitor whose
value has been chosen to pass the necessary IF
frequency range. For operation to DC, this pad
must not source/sink more than 3mA of current or
die non-function and possible die failure will result.
Pads 5 and 6 are alternate IF ports.
The backside of the die must be connected
to RF/DC ground.
