Functional Diagram
General Description
The HMC329 chip is a miniature passive double
balanced mixer which can be used as an upcon-
verter or downconverter from 25-40 GHz in a
small chip area of 0.84mm x 0.55mm. 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 鏗亁ture 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).
