Abstract :
In this paper we describe experimental investigations of a driven TWT feedback amplifier as a candidate source of wideband, high power, chaotic radiation. Experimental observations and characterizations include time-domain waveforms and waveform phase plots, FFT spectra and Poincare maps at varying levels of feedback.
