Efficient Simulation of Millimeter-Wave IMPATT Oscillators by FATE, a Combined Time- and Frequency-Domain Method

The FATE method, proposed by M. Schwab (IEEE Trans. Microwave Theory and Techniques, vol.39, no.8, p.1391-402, 1991), for the determination of the periodic state in oscillators is shown to be ideally suited for the simulation of oscillators with strongly nonlinear active devices, e.g. IMPATT oscillators. Simulations of a waveguide oscillator illustrate the choice of a favorable network partition and the advantage of the bandwidth-unlimited time-domain simulation of the nonlinear subnetwork. V-band hybrid-integrated IMPATT oscillator simulation results are presented, showing agreement in output power within 4 dB over the DC current range from 100 mA to 220 mA compared to the measured levels and a time-domain simulation.textlesstextlessETXtextgreatertextgreater     «
