General Description
The HMC560 chip is a miniature passive double
balanced mixer which is fabricated in a GaAs MESFET
process, and can be used as an upconverter or
downconverter 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.
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 micro-
strip test fixture. Measured data includes the parasitic
effects of the assembly. RF connections to the chip
were made with 0.076mm (3-mil) ribbon bond with
minimal length <0.31mm (<12 mil).
Electrical Specifications, T_A = +25° C, IF = 1GHz, LO = +13 dBm*
