Download or read book Feedback Linearization of RF Power Amplifiers written by J.L. Dawson and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improving the performance of the power amplifier is the most pressing problem facing designers of modern radio-frequency (RF) transceivers. Linearity and power efficiency of the transmit path are of utmost importance, and the power amplifier has proven to be the bottleneck for both. High linearity enables transmission at the highest data rates for a given channel bandwidth, and power efficiency prolongs battery lifetime in portable units and reduces heat dissipation in high-power transmitters. Cartesian feedback is a power amplifier linearization technique that acts to soften the tradeoff between power efficiency and linearity in power amplifiers. Despite its compelling, fundamental advantages, the technique has not enjoyed widespread acceptance because of certain implementation difficulties. Feedback Linearization of RF Power Amplifiers introduces new techniques for overcoming the challenges faced by the designer of a Cartesian feedback system. The theory of the new techniques are described and analyzed in detail. The book culminates with the results of the first known fully integrated Cartesian feedback power amplifier system, whose design was enabled by the techniques described. Feedback Linearization of RF Power Amplifiers is a valuable reference work for engineers in the telecommunications industry, industry researchers, academic researchers.

Download or read book Dynamic Power Supply Transmitters written by Earl McCune and published by Cambridge University Press. This book was released on 2015-05-21 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Power is dissipated (lost) when this current flows through any resistance, which includes the amplifier's transistor. This dissipated power is the product of the current in the load times the voltage difference between the supply voltage to the amplifier and the output signal voltage. When the voltage supplied to the amplifier is a constant value, and by far the most common design practice, the situation in Fig. 1-2a results. Power dissipation in the amplifier is maximum when the output signal voltage is 1/2 of the supply voltage. When the output signal voltage is higher, even though the current value is larger the voltage drop is less and the power dissipation is lower. Similarly, when the output signal voltage is small, even though the voltage drop is now large the current in the load is smaller and again the power dissipation is lower"--

Download or read book Nonlinear Design FETs and HEMTs written by Peter H. Ladbrooke and published by Artech House. This book was released on 2021-11-30 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite its continuing popularity, the so-called standard circuit model of compound semiconductor field-effect transistors (FETs) and high electron mobility transistors (HEMTs) is shown to have a limitation for nonlinear analysis and design: it is valid only in the static limit. When the voltages and currents are time-varying, as they must be for these devices to have any practical use, the model progressively fails for higher specification circuits. This book shows how to reform the standard model to render it fully compliant with the way FETs and HEMTs actually function, thus rendering it valid dynamically. Proof-of-principle is demonstrated for several practical circuits, including a frequency doubler and amplifiers with demanding performance criteria. Methods for extracting both the reformulated model and the standard model are described, including a scheme for re-constructing from S-parameters the bias-dependent dynamic (or RF) I(V) characteristics along which devices work in real-world applications, and as needed for the design of nonlinear circuits using harmonic-balance and time-domain simulators. The book includes a historical review of how variations on the standard model theme evolved, leading up to one of the most widely used—the Angelov (or Chalmers) model.

Download or read book Substrate Integrated Suspended Line Circuits and Systems written by Kaixue Ma and published by Artech House. This book was released on 2024-03-31 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Substrate Integrated Suspended Line Circuits and Systems provides a systematic overview of the new transmission line - the substrate-integrated suspension line (SISL). It details the fundamentals and classical application examples of the SISL. The basic SISL concept and structure, various passive circuits and active circuits, and front-end sub-systems are systematically introduced. Featuring research on topics such as high-performance RF/microwave/mm-wave circuits and system, this book is ideal for researchers, engineers, scientists, scholars, educators, and students. Since transmission line is a fundamental component of microwave and mm-wave circuits, the properties of a transmission line, such as losses, size, and dispersion, are vital to the performance of the whole system. Suspended line has been proved to be an excellent transmission line, as it has attractive features such as low loss, weak dispersion, high power capacity, and low effective dielectric constant. However, Conventional waveguide suspended line circuits require metal housing to form air cavities which is Substrate Integrated Suspended Line Circuits and Systems essential to the operation of suspended lines circuits. Also, the metal shell should provide mechanical support and shielding, which contribute to large size and heavy weight. Meanwhile, precise mechanical fabrication and assembling are strongly required, which brings difficulties to the design and fabrication of conventional suspended line circuits, and the manufacturing cost of suspended line circuits increases correspondingly. In this book, we will introduce a new platform of high-performance transmission line, i.e. substrate integrated suspended line (SISL). SISL keeps all the merits of the suspended line while overcomes the drawbacks of conventional waveguide suspended line circuits. Moreover, it is self-packaged and highly integrated. The basic SISL concept and structure, various passive circuits and active circuits, and front-end sub-systems will be systematically introduced. Featuring research on topics such as high-performance RF/microwave/mm-wave circuits and system, this book is ideally designed for researchers, engineers, scientists, scholars, educators, and students.
