General Description
The HMC329 chip is a miniature passive double
balanced mixer which can be used as an
upconverter or downconverter from 25 - 40 GHz
in a small chip area of 0.84 mm x 0.55 mm.
Excellent isolations are provided by on-chip
baluns, and the chip requires no external components and no DC bias. The mixer chip is
designed to be used in Local Multi- Point Distribution Systems (LMDS), microwave point to
point radios, and SATCOM applications. Measurements were made with the chip mounted
and ribbon bonded into in a 50-ohm microstrip
test fixture that contains 5-mil alumina substrates between the chip and K-connectors.
Measured data includes the parasitic effects of
the assembly. RF connections to the chip were
made with 0.076 mm (3-mil) ribbon bond with
minimal length <0.31mm (<12 mil).
