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(R) 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.

Описание: Broadband -- whether delivered via fiber, cable modem, mobile or fixed wireless, copper wire, or satellite -- is increasingly the technology underlying telecommunications services such as voice, video, and data. Chapter 1 focuses on the gaps specifically related to broadband availability and adoption. How broadband is defined and characterized in statute and in regulation can have a significant impact on federal broadband policies and how federal resources are allocated to promote broadband deployment in unserved and underserved areas as discussed in chapter 2. The move to place restrictions on the owners of the networks that comprise and provide access to the internet, to ensure equal access and nondiscriminatory treatment, is referred to as "net neutrality." While there is no single accepted definition of net neutrality most agree that any such definition should include the general principles that owners of the networks that comprise and provide access to the internet should not control how consumers lawfully use that network; and should not be able to discriminate against content provider access to that network as reported in chapters 3 and 4. The "digital divide" is a term that has been used to characterize a gap between "information haves and have-nots," or in other words, between those Americans who use or have access to telecommunications and information technologies and those who do not. Chapter 5 focuses on the one important subset of the digital divide debate which concerns high-speed internet access and advanced telecommunications services, also known as broadband. While there are many examples of rural communities with state-of-the-art telecommunications facilities, recent surveys and studies have indicated that, in general, rural areas tend to lag behind urban and suburban areas in broadband deployment. The Rural Utilities Service (RUS) at the U.S. Department of Agriculture (USDA) houses three ongoing assistance programs exclusively created and dedicated to financing broadband deployment: the Rural Broadband Access Loan and Loan Guarantee Program, the Community Connect Grant Program, and the ReConnect Program. Chapter 6 discusses each of these programs. Tribal lands are generally in remote and rugged areas and broadband access can help residents develop online businesses, access telemedicine services, and use online educational tools. However, residents of tribal lands have lower levels of broadband access than residents of non-tribal lands. Chapters 7 through 11 report on the status of broadband on tribal lands.

Описание: The access network is expected to be one of the major battlegrounds of telecommunications network operators, since upgrades of the existing narrowband access network will be the critical factor in supplying multimedia broadband services in a competitive market.

This book describes the background and technology of array signal modeling. It presents the concept and formulation of beamformers and discusses several commonly used array performance measures. It also introduces two traditional types of beamformers: delay-and-sum and optimum beamformers.
Chapter 1 includes background information on array processing, while Chapters 2 and 3 discuss the DFT-based frequency-domain implementation of a broadband beamformer and the design of subband beamformers for frequency-domain broadband beamformers. Chapter 4 presents the FIR-based, time-domain implementation of the broadband beamformer, where the FIR beamformer is designed by separately designing the subband beamformers and the corresponding FIR filters. The techniques for optimal design of the FIR beamformer are developed in Chapter 5, and Chapters 6 and 7 focus on the modal beamforming problem for circular arrays for the frequency-domain modal beamformer and the time-domain modal beamformer. Lastly, the final chapters present frequency-domain and time-domain modal beamformers for spherical arrays.
