3D momentum modeling technique and measurements of CPW compact GaAs multilayer MMICs

New electromagnetic modeling technique using 3D momentum optimization has been developed to accurately model compact multilayer coplanar waveguide (CPW) MMICs. Suitable layout simulation setups are provided which showed good agreements with the measured data. Furthermore, a TOM3 schematic design of a MMIC GaAs pHEMT has been developed and compared with its TOM3 netlist file along with the measured results. The fabricated multilayer MMIC amplifier has also been characterized and compared with the simulation data. In addition, we demonstrate the utilization of the optimized amplifier model in understanding parasitic inductance in the on-wafer measurement.
