This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Wide bandgap silicon-carbide (SiC) and gallium-nitride (GaN) FETs are the premier microwave solid-state power technology and are presently being deployed in a variety of commercial applications. However, performance-degrading self-heating and charge-trapping effects create new challenges for characterization and modeling of these devices. Accurate nonlinear models capable of predicting these effects are necessary to maximally exploit the benefits of this emerging, high power density technology. An empirical modeling methodology for the SiC MESFET and GaN HEMT using high power dynamic IV measurements to exploit and characterize self-heating and charge-trapping is applied over a vast range of electrothermal operating conditions. Nonlinear diode modeling and multibias, small-signal techniques are performed to create complete nonlinear models for SiC and GaN FETs, which are capable of predicting DC, pulsed, small- and large-signal RF behavior over a wide range of bias and frequency. The presented models are valid for drain currents beyond 2A, drain voltages greater than 50V and up to 10W at RF. These harmonically-accurate models permit the new application of CAD-based active frequency multiplier design for wide bandgap devices. Frequency doublers and triplers are demonstrated in SiC MESFET and GaN HEMT technology, producing some of the highest power, single-transistor microwave frequency multipliers to date. This work reports SiC- and GaN-based C-band frequency doublers with>5W output power and a GaN-based X-band frequency tripler with 1W output power.

Available in PDF, EPUB and Kindle. Book excerpt: Design techniques for nonlinear microwave circuits are much less developed than for linear microwave circuits. Until now there has been no up-to-date text available in this area. Current titles in this field are considered outdated and tend to focus on analysis, failing to adequately address design and measurement aspects. Giannini and Leuzzi provide the theoretical background to non-linear microwave circuits before going on to discuss the practical design and measurement of non-linear circuits and components. Non-linear Microwave Circuit Design reviews all of the established analysis and characterisation techniques available and provides detailed coverage of key modelling methods. Practical examples are used throughout the text to emphasise the design and application focus of the book. Provides a unique, design-focused, coverage of non-linear microwave circuits Covers the fundamental properties of nonlinear circuits and methods for device modelling Outlines non-linear measurement techniques and characterisation of active devices Reviews available design methodologies for non-linear power amplifiers and details advanced software modelling tools Provides the first detailed treatment of non-linear frequency multipliers, mixers and oscillators Focuses on the application potential of non-linear components Practicing engineers and circuit designers working in microwave and communications engineering and designing new applications, as well as senior undergraduates, graduate students and researchers in microwave and communications engineering and their libraries will find this a highly rewarding read.

Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear models of microwave transistors are essential for the design of high-frequency nonlinear circuits, such as power amplifiers or mixers. Among the existing modeling techniques, measurement-based approaches have gained huge attention from researchers in the last decades. Especially, nonlinear measurements-driven model extraction is preferred for transistors exploited in the design of power amplifiers and mixers. This chapter mainly deals with the generation of empirical transistor models starting from large-signal time-domain waveforms. Specifically, a widely used model available in commercial CAD tools is adopted, and the extraction procedure of the model parameters is outlined in detail. Moreover the advantage of using time-domain waveforms at different frequencies is highlighted. More specifically, by making use of time-domain waveforms at frequencies in the kHz-MHz range, one can separately model the behavior of the transistor output current generator, which is more prone to low-frequency dispersive effects. In fact at low frequencies the effect of the nonlinear transistor capacitance is significantly reduced and, therefore, already “de-embedded” from the measured time-domain waveforms. Once the model of the output current generator is available, one can use high-frequency measurements to determine the nonlinear capacitances (or charges). Several modeling examples of different transistor technologies, such as gallium-arsenide and gallium-nitride, are reported.

Download or read book Nonlinear Active Microwave Circuits written by T. Berceli and published by Elsevier Publishing Company. This book was released on 1987 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents analysis and design methods of microwave nonlinear active circuits. Nonlinear models are established for each individual device, thus introducing a set of nonlinear building blocks. This allows not only qualitative but also quantitative investigations. The relationships thereby obtained can be used for design purposes, and they are also a help in understanding the circuit operation and for the detailed investigation of oscillators, amplifiers, mixers, frequency multipliers and dividers. The book concentrates on problems arising from the active nonlinear elements, and it is mostly nonlinear transmission properties that are investigated. Normalized quantities are applied in order to obtain results that can be used generally for a wide range of applications. Equations are derived for many important circuit characteristics such as bandwidth, gain, amplitude and phase response, group delay time, AM compression, AM to PM conversion, noise figure, AM noise, FM noise, output power, added power, efficiency, matching, optimum adjustment, stability, dynamic properties. The results are directly applicable in the design procedure of circuits.

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.

The complexity requirements of future wireless communication systems now indeed demand a more general theoretically robust design methodology for nonlinear circuits, such as the power amplifiers. The present design methodology for nonlinear Radio Frequency components and circuits has become a key hindrance in the evaluation, development and testing of modern communication systems. The fundamental nature of this engineering challenge makes it highly unlikely to be addressed within the competitive Radio Frequency industry with short-term profitability, time to market and risk aversion considerations.

The book , therefore, includes developing advanced waveform measurement setups, multi-tone measurement techniques, characterization and modelling of nonlinear distortion in microwave power transistors and design of high-power and spectrum-efficient RF power amplifiers for future wireless communication systems. Further enlists the key impediments in Power Amplifier design through the application of waveform engineering to embrace simultaneously efficiency and linearity objectives of power amplifier design as well as investigate the most robust and appropriate behavioral model formulation that includes memory effects.
