General Description
The HMC560 chip is a miniature passive double bal-
anced mixer which is fabricated in a GaAs MESFET
process, and can be used as an upconverter or down-
converter from 24-40 GHz in a small chip area. The
wide bandwidth allows this device to be used across
multiple radio bands with a common platform. Excel-
lent 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 micro-
strip test fixture. Measured data includes the parasi-
ticeffects of the assembly. RF connections to the chip
were made with 0.076mm (3-mil) ribbon bond with
minimal length <0.31mm (<12 mil).
