The Operation of S-Band TRAPATT Oscillators with Tuning at Multiple Harmonic Frequencies (Short Pape

A simplified TRAPATT oscillator model that allows the investigation of arbitrary terminal waveforms was utilized to investigate realistic TRAPATT waveforms and the tuning conditions necessary for high-efficiency operation. The effects of the higher harmonics on oscillator frequency and efficiency were studied. Cicuit impedance measurements of S-band TRAPATT oscillators support the theoretical predictions.
