Abstract
Pulsed high-power radio frequency (rf) systems frequently employ pulse compressors to augment peak output power, thereby reducing the required number of rf sources and enhancing cost efficiency. A prominent class of these devices utilizes single resonant cavities supporting two degenerate modes to achieve high performance within a compact footprint. However, the inherent coupling of these modes complicates experimental characterization, a challenge exacerbated by the fact that these units are typically nondismountable. This paper proposes a novel analytical method to disentangle the complex electromagnetic data encoded within these systems. By separately extracting the parameters of the individual degenerate modes and the characteristics of the associated waveguide network, the method provides a granular view of device performance. This approach enables a more comprehensive interpretation of measurement data, offering a pathway for the precise tuning and optimization of monolithic rf pulse compression systems.
