Functional Diagram
General Description
The HMC292 chip is a miniature passive GaAs MMIC
double-balanced mixer which can be used as an
upconverter or downconverter from 18 - 32 GHz in a
small chip area of 0.66 mm
2
. Excellent isolations are
provided by on-chip baluns, which require no exter-
nal components and no DC bias. All data is measured
with the chip in a 50 ohm test fixture connected via
0.076 mm (3 mil) ribbon bonds of minimal length <0.31
mm (<12 mils).

IF
This pin 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 pin must not source/
sink more than 2 mA of current or die non-function and possible
die failure will result.
Die Bottom
GND
Die bottom must be connected to RF/DC ground.
