Klystron, Reflex, Integral Cavity, 8.1-12.4 GHz (WR-90), X Band, 100mW Varian #X-13 Reflex Klystrons Klystrons are velocity modulated tubes designed to overcome the frequency limits of traditional grid tubes. Any linear beam klystron may operate as oscillator adding a feedback connection between output and input cavities. But when a klystron must just be operated as oscillator its structure may be simplified, leaving only one gap and negatively biasing the electrode that before was the collector. In this type of tube, referred to as reflex klystron, the negative electrode is called repeller. Electrons that have already crossed the gap, being consequently bunched, are forced by repeller to cross back the same gap that now performs the function of catcher. As for linear beam devices, also reflex klystrons were built in a variety of types. Many came with integral or factory installed resonator, while other were designed for mounting into external resonating cavities, supplied by the manufacturer of the equipment. Reflex klystrons of the first type were available over an extremely extended range of frequencies, usually for small and medium output power, and have been widely used as local oscillator in microwave receivers or even in communication relay equipment. X-13 from Varian was intended as a precision source tunable from 8.2 to 12.4 GHz. DESCRIPTION The X-13 micrometer-tuned reflex klystron is a power source for microwave tests and measurements. It delivers a CW output of at least 100 milliwats under optimum load conditions over the frequency range of 8.1 to 12.4 gigahertz. The very wide tuning range and ample power output provide the versatility required for its use as a general-purpose microwave power source. The low-current heater assures long tube life and excellent over-all efficiency.
