Barkhausen model of Reflex Klystron Oscillator

Reflex Klystron is an oscillator commonly classified under the categories of differential negative conductance oscillators, like Tetrode Oscillator, Gunn Oscillators etc., whereas the Barkhausen oscillator is categorized under the positive feedback system. With the help of physics positive feedback nature of Reflex Klystron, the growth of oscillation leading to its spectral purification and the effect of transit time delay are discussed here. The dependence of Pole-location, Pole-movement, Starting voltage and Jump-phenomenon, hitherto unknown, on mode number has been given.
