This book was released on 2011 with total page 883 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microwave tubes are vacuum electron devices used for the generation and amplification of radio frequencies in the microwave range. An established technology area, the use of tubes remains essential in the field today for high-power applications. The culmination of the authorOCOs 50 years of industry experience, this authoritative resource offers you a thorough understanding of the operations and major classes of microwave tubes.Minimizing the use of advanced mathematics, the book places emphasis on clear qualitative explanations of phenomena. This practical reference serves as an excellent introduction for newcomers to the field and offers established tube engineers a comprehensive refresher. Professionals find coverage of all major tube classifications, including klystrons, traveling wave tubes (TWTs), magnetrons, cross field amplifiers, and gyrotrons."

Download or read book Reduction of Noise in Crossed field Microwave Amplifiers written by Niladri Raju Mantena and published by . This book was released on 1966 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conditions for low-noise operation are established to be the following: (1) the use of a well-focused beam, (2) reduction of the diocotron gain of the gun and drift regions to a minimum possible value, (3) full exploitation of magnetic and space-change smoothing for maximum reduction of noise figure, (4) launching the beam very close to the circuit, (5) reducing the space-charge parameter S close to zero, (6) high power gain, and (7) minimizing the initial beam position fluctuations by reducing the cathode thickness. By combining optimum beam focusing, space-charge smoothing, and beam displacement, low noise figures of 10.5 db for the backward-wave amplifier and 18.4 db for the forward-wave amplifier have been obtained without using noise transducers. A better control of the above factors than was possible with the present experimental tube will result in still lower noise figures. With the noise transducing scheme added to the factors listed above, it should be possible to obtain extremely low noise figures as was done by Wadhwa and Van Duzer. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Crossed-field Microwave Devices, Volume I: Principal Elements of Crossed-Field Devices focuses on the developments, trends, and approaches in the study of crossed-field microwave devices. The selection first offers information on periodic structures and cathode gun and its static characteristics. Discussions focus on circuits for traveling wave crossed-field tubes; effect of tolerance on interdigital lines; mode spectrum of strapped type magnetron; and electron gun optics and associated static characteristics of injection systems. The text then takes a look at noise and space-charge modes, including preoscillation phenomena in space-charge clouds below the main oscillation threshold; cutoff characteristics of the static magnetron diode; magnetron diode oscillations; and noise in crossed-field electron beams. The manuscript then examines the interaction of beams and circuits, as well as small and large signal theory and experiment. The selection is a valuable reference for readers interested in the elements of crossed-field microwave devices.
