Video Pulse Conversion Into A Radio Frequency Pulsed Waveform Of Complex Composition

The paper is a feasibility study for a nonlinear wave guiding structure, based on a coaxial line with a magnetized ferrite core inside, to form broadband pulsed signals with a controllable radio-frequency spectrum. A set of two serially connected coaxial guides of different diameters of order 101 mm is analyzed, where the ferromagnetic is subjected to an axial magnetizing field and the azimuthal field belonging to the initially incident video pulse. Possibilities have been demonstrated for a targeted alteration, over a broad band like Δf/f = 0.25…0.55, of the waveform and gigahertz-range frequency spectrum of the output signal. In case of employing a feeding high-voltage signal of relatively short duration it may become possible to implement the Peak Power Amplification operating mode. (author)
