Download or read book Efficiency Enhancement in Megawatt Level Broadband Microwave Amplifiers written by Robert J. Butwell and published by . This book was released on 1974 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report covers effort expended on a theoretical and experimental investigation of methods of improving the conversion efficiency of relatively broadband linear-beam amplifiers operating at approximately 1 Mw of peak power. A design was achieved using a 'short-stack' intense- approximately 1 Mw of peak power. A design was achieved using a 'short-stack' intense-interaction cloverleaf structure; a forward-fundamental, coupled-cavity circuit. Computer-aided calculations predicted 40% minimum efficiency over a 9% bandwidth with a midband efficiency greater than 60%.

Available in PDF, EPUB and Kindle. Book excerpt: Broadband RF and Microwave Amplifiers provides extensive coverage of broadband radio frequency (RF) and microwave power amplifier design, including well-known historical and recent novel schematic configurations, theoretical approaches, circuit simulation results, and practical implementation strategies. The text begins by introducing two-port networks to illustrate the behavior of linear and nonlinear circuits, explaining the basic principles of power amplifier design, and discussing impedance matching and broadband power amplifier design using lumped and distributed parameters. The book then: Shows how dissipative or lossy gain-compensation-matching circuits can offer an important trade-off between power gain, reflection coefficient, and operating frequency bandwidth Describes the design of broadband RF and microwave amplifiers using real frequency techniques (RFTs), supplying numerous examples based on the MATLAB® programming process Examines Class-E power amplifiers, Doherty amplifiers, low-noise amplifiers, microwave gallium arsenide field-effect transistor (GaAs FET)-distributed amplifiers, and complementary metal-oxide semiconductor (CMOS) amplifiers for ultra-wideband (UWB) applications Broadband RF and Microwave Amplifiers combines theoretical analysis with practical design to create a solid foundation for innovative ideas and circuit design techniques.

Available in PDF, EPUB and Kindle. Book excerpt: RF power amplifiers (PA) are among the key building blocks for wireless communication systems. Current digital communication standards need both high linearity and power efficiency. Generally, there is a conflict between the linearity and efficiency of power amplifiers. The Chireix's outphasing power amplifier is one of the promising techniques that can be used as a linearization and efficiency enhancement technique.
