This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A new nonlinear dynamic model of large-signal amplifiers based on a Volterra-like integral series expansion is described. The new Volterra-like series is specially oriented to the modeling of nonlinear communication circuits, since it is expressed in terms of dynamic deviations of the complex modulation envelope of the input signal. The proposed model represents a generalization, to nonlinear systems with memory, of the widely-used amplitude/amplitude (AM/AM) and amplitude/phase (AM/PM) conversion characteristics, which are based on the assumption of a practically memoryless behavior. A measurement procedure for the experimental characterization of the proposed model is also outlined.

Book Synopsis Nonlinear System Identification and Analysis with Applications to Power Amplifier Modeling and Power Amplifier Predistortion by : Raviv Raich
Download or read book Nonlinear System Identification and Analysis with Applications to Power Amplifier Modeling and Power Amplifier Predistortion written by Raviv Raich and published by . This book was released on 2004 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power amplifiers (PAs) are important components of communication systems and are inherently nonlinear. When a non-constant modulus signal goes through a nonlinear PA, spectral regrowth (broadening) appears in the PA output, which in turn causes adjacent channel interference (ACI). Stringent limits on the ACI are imposed by regulatory bodies, and thus the extent of the PA nonlinearity must be controlled. PA linearization is often necessary to suppress spectral regrowth, contain adjacent channel interference, and reduce bit error rate (BER). This dissertation addresses the following aspects of power amplifier research: modeling, linearization, and spectral regrowth analysis. We explore the passband and baseband PA input/output relationships and show that they manifest differently when the PA exhibits long-term, short-term, or no memory effects. The so-called quasi-memoryless case is especially clarified. Four particular nonlinear models with memory are further investigated. We provide experimental results to support our analysis. The benefits of using the orthogonal polynomials as opposed to the conventional polynomials are explored, in the context of digital baseband PA modeling and predistorter design. A closed-form expression for the orthogonal polynomial basis is derived. We demonstrate the improvement in numerical stability associated with the use of orthogonal polynomials for predistortion. Spectral analysis can help to evaluate the suitability of a given PA for amplifying certain signals or to assist in predistortion linearization algorithm design. With the orthogonal polynomials that we derived, spectral analysis of the nonlinear PA becomes a straightforward task. We carry out nonlinear spectral analysis with digitally modulated signal as input. We demonstrate an analytical approach for evaluating the power spectra of filtered QPSK and OQPSK signals after nonlinear amplification. Many communications devices are nonlinear and have a peak power or peak amplitude constraint. In addition to possibly amplifying the useful signal, the nonlinearity also generates distortions. We focus on signal-to-noise-and-distortion ratio (SNDR) optimization within the family of amplitude limited memoryless nonlinearities. We obtain a link between the capacity of amplitude-limited nonlinear channels with Gaussian noise to the SNDR.
Book Synopsis High Efficiency Linear/nonlinear Power Amplifier Design with Distributed Elements by : Adnan Kantemur
Download or read book High Efficiency Linear/nonlinear Power Amplifier Design with Distributed Elements written by Adnan Kantemur and published by . This book was released on 2013 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio Frequency Power Amplifiers (RF PAs) are inevitable part of the any wireless communication systems. As new requirements increases, new challenges presents for PA designers. The main issue for designing a PA is to have highly linear and high efficient design at same time to have high output power and power gain. When we talk about linear PAs, most of the time they are easy to complete the design with S parameters but they have low efficiency. On the other hand, if we go further in the frequency domain, it is difficult to find stable lumped elements. In this case, it is better to complete design with distributed elements but since we are dealing with high power, distribute elements may not handle high temperature. Therefore design should complete carefully. The small signal S parameters are not suitable for power amplifier (PA) design because most of the high efficiency PAs are operate in the nonlinear region. Therefore new form of S parameters should be defined under large signal input. Hence, an alternative set of large signal parameters is needed to characterize the transistor. This can be only done by providing source and load reflection coefficients as a function of output power and gain. The way of finding proper source/load reflection coefficient is applying load/source pull measurement. In this measurement,source and load of the transistor connects to a tuner and input power level changes by helping of a software output power contours can be observe and optimum load/source reflection coefficients can be obtained. This measurement should be done not only for fundamental frequency but also harmonics; especially second and third harmonics have critical effect on the efficiency of the transistor. To achieve highly efficient PA these harmonics should be suppressed. This is can be done with harmonic matching networks. To other problem when we talk about PA is high power, since we need high power input stage our device should handle high power. This is one of limitation of a transistor. Beauty of GaN FET is can work under very high power level. GaN transistors are stable in very high temperature that makes these devices must have component in the PA design.
