Abstract

Newly measured data for the loss of microstrip on 4 mil GaAs from DC to 40 GHz are presented. These data were taken from transmission measurements of lightly coupled, multiple-half-wave-length resonators. A comparison of the loss data with the predicted losses from three popular CAE (computer-aided engineering) tools is provided. The loss models provided by two out of three software vendors agree fairly well with measured data through 40 GHz. Since the measured loss roughly follows a square-law frequency relationship through 20 GHz, it should be possible to adjust the loss below this frequency and above 1 GHz by modifying the resistivity of the conductor in the simulator
