Book Synopsis Nonlinear Traveling Wave Tube Analysis with Two Signal Frequencies by : Sven Wallander
Download or read book Nonlinear Traveling Wave Tube Analysis with Two Signal Frequencies written by Sven Wallander and published by . This book was released on 1966 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mutual nonlinear distortion of two simultaneous signals in a TWT is theoretically investigated. It is shown that minimum phase distortion occurs at a low beam voltage while minimum amplitude distortion occurs at a high beam voltage. The mutual distortion dominated over the self distortion.

Book Synopsis Nonlinear Multi-Signal Traveling Wave Tube Theory by : Sven Wallander
Download or read book Nonlinear Multi-Signal Traveling Wave Tube Theory written by Sven Wallander and published by . This book was released on 1969 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report gives an analysis of the nonlinearities arising in a TWT with N input signals. The signal frequencies are assumed to be confined within a narrow frequency band. The sum of the input signals is then equivalent to a single signal with a slow modulation of the amplitude and the phase and the multi-signal nonlinearities can be predicted from the single-signal nonlinearities. These have been theoretically calculated in an earlier paper. Fifth order power series expansions of the single-signal nonlinearities are used. Minimum amplitude nonlinearities are obtained for a beam voltage higher than that giving maximum small signal gain and minimum phase shift nonlinearities are obtained for a beam voltage lower than that. The power of the third and fifth order modulation products is minimum for a beam voltage between that for maximum small signal gain and that for minimum amplitude nonlinearities. The 'self-distortion', i.e. the compression and the AM-to-PM conversion of one of the signals, is strongly influenced by the total power carried by the other signals. The cross-distortion quantities are generally about twice as large as the self-distortion quantities. (Author).

Download or read book Spacecraft TT&C and Information Transmission Theory and Technologies written by Jiaxing Liu and published by Springer. This book was released on 2014-09-04 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spacecraft TT&C and Information Transmission Theory and Technologies introduces the basic theory of spacecraft TT&C (telemetry, track and command) and information transmission. Combining TT&C and information transmission, the book presents several technologies for continuous wave radar including measurements for range, range rate and angle, analog and digital information transmissions, telecommand, telemetry, remote sensing and spread spectrum TT&C. For special problems occurred in the channels for TT&C and information transmission, the book represents radio propagation features and its impact on orbit measurement accuracy, and the effects caused by rain attenuation, atmospheric attenuation and multi-path effect, and polarization composition technology. This book can benefit researchers and engineers in the field of spacecraft TT&C and communication systems. Liu Jiaxing is a professor at The 10th Institute of China Electronics Technology Group Corporation.
Book Synopsis Crossed-field Microwave Devices V3 by : G Mourier
Download or read book Crossed-field Microwave Devices V3 written by G Mourier and published by Elsevier. This book was released on 2012-12-02 with total page 671 pages. 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.

Book Synopsis Crossmodulation in Traveling Wave Tubes by : Jan Ingvar Lindström
Download or read book Crossmodulation in Traveling Wave Tubes written by Jan Ingvar Lindström and published by . This book was released on 1968 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of crossmodulation effects in a commercial medium power S-band TWT are reported. The tube was fed with two simultaneous monochromatic input signals of frequencies 2.15 and 3.80 GHz. The relations between the crossmodulation and the nonlinear distortion with only one of the signals present are investigated and are found to be in very good agreement with a theoretical analysis. For the two signal case the nonlinear amplitude and phase distortions in various representations (compression, AM-to-PM crossconversion etc.) are given as functions of parameters like the helix voltage and the output power. It is confirmed that a low helix voltage gives low AM-to-PM conversion and low AM-to-PM crossconversion, while a high helix voltage gives a good amplitude linearity, i.e. low compression and amplitude crossmodulation.

Book Synopsis Simulation of Communication Systems by : Michel C. Jeruchim
Download or read book Simulation of Communication Systems written by Michel C. Jeruchim and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 920 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first edition of this book was published seven years ago, the field of modeling and simulation of communication systems has grown and matured in many ways, and the use of simulation as a day-to-day tool is now even more common practice. With the current interest in digital mobile communications, a primary area of application of modeling and simulation is now in wireless systems of a different flavor from the `traditional' ones. This second edition represents a substantial revision of the first, partly to accommodate the new applications that have arisen. New chapters include material on modeling and simulation of nonlinear systems, with a complementary section on related measurement techniques, channel modeling and three new case studies; a consolidated set of problems is provided at the end of the book.
