Functional Diagram
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 0.85 x 0.55 mm. Excellent isolations are
provided by on-chip baluns, and the chip requires no
external components and no DC bias. 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).
