This book was released on 2005 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling and characterization strategies were developed to capture the complex nonlinear behavior of both the components within an RF circuit and within an assembled system. Metrology techniques using common laboratory instrumentation were developed for the remote characterization of assembled RF devices and the result of this characterization is presented here for the first time. In addition, two novel intermodulation relative phase measurement systems were developed that have 90 dB of dynamic range which is a considerable improvement over existing systems. This enables the measurement of weaker nonlinearities and increases the accuracy of these measurements. A behavioral modeling architecture and extraction procedure were developed to take advantage of the metrology techniques to allow the separation of odd-ordered nonlinear effects and baseband upconversion effects in several amplifiers. The results of applying this modeling strategy has produced a general model capable of predicting both magnitude and phase asymmetries in nonlinear components for the first time. Concepts from the remote characterization, intermodulation phase measurement systems, and the modeling efforts were combined to demonstrate the extraction of two-port transmission parameters from one-port measurements in an archetypal circuit of an integrated bandpass filter in an RF front-end. It is shown how this information can be used to tune a filter.

Book Synopsis Microwave De-embedding by : Wendy Van Moer
Download or read book Microwave De-embedding written by Wendy Van Moer and published by Elsevier Inc. Chapters. This book was released on 2013-11-09 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world is often considered to behave approximately linearly. However, many real-life phenomena are inherently nonlinear! Hence, in order to accurately model the true behavior of a radio-frequency device or system, its nonlinear characteristics can no longer be ignored and should be taken into account. To do so, one should first be able to measure these nonlinear effects. After some years of hesitation, the high-frequency measurement world finally acknowledged the necessity to accurately measure the in- and out-of-band nonlinear behavior of a radio-frequency (RF) device or system. Since then, different measurement approaches have been developed to achieve this goal. The two major measurement principles being pursued are the sampler-based and the mixer-based methodology. The calibration and de-embedding process of nonlinear measurements is quite involved and requires special calibration standards. From the acquired “nonlinear” measurement data, one can then build a model that accurately describes the in-band and out-of-band nonlinear behavior of an RF system. This chapter will show the reader how to do accurate nonlinear RF measurements and how to obtain a simple and robust characterization of the nonlinear behavior of an RF system.

Book Synopsis Modular Nonlinear Characterization System and Large-signal Behavioral Modelling of Unmatched Transistors for Streamlined Power Amplifier Design by : Dylan Bespalko

This book was released on 2016 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis provides a comprehensive approach to the characterization and modelling of large-signal nonlinear RF/microwave devices, circuits and systems. This research is moti- vated by the increased linearity and power-efficiency requirements of modern power ampli- fier technology for wireless communications. For instance, maximizing the power amplifier's efficiency can only be achieved by operating RF transistors under strong nonlinear condi- tions, however this is contradictory to maximizing PA linearity. Simultaneously designing for efficiency and linearity is a challenging trade-off in today's fragmented design process, therefore the advancement of computer-aided design (CAD) tools is essential for achieving an optimal solution. The successful and effective CAD tool based PA design relies on the availability of accurate nonlinear models to mimic the electro-thermal behaviour of RF transistors. The accuracy of these models depends on three factors: 1. The formulation of the model. 2. The model extraction procedure. 3. The accuracy of the measurement data. While prior work focuses separately on the improved model formulations or improving characterization accuracy, this thesis provides a comprehensive analysis of all three factors. This thesis proposes a modular large-signal RF device characterization system, and a non- linear behavioral model capable of handling strongly nonlinear unmatched RF transistors, each necessary to streamline the design process and achieve a first-pass PA design. iii As a first step, a large-signal characterization system has been developed to measure the multi-harmonic frequency response of RF transistors and has the ability to i) Perform high-power measurements, ii) Characterize unmatched transistors, iii) Operate the DUT under any possible operating condition, iv) Synthesize any multi-harmonic stimulus, and v) Reconstruct the time-domain I/V waveforms at the ports of the DUT. The proposed characterization system eliminates fragmentation between measurement and simulation environments by providing seamless integration with Harmonic Balance simulations. This provides a common framework that integrates all steps of the PA design process from device-level characterization, to circuit-level measurement and validation. This system is implemented using modular instruments consisting of mixer-based receivers, arbitrary waveform generators, impedance tuners, and a multi-harmonic phase-coherent reference source. It also integrates sequential calibration routines to provide receiver, port match, and source-power corrections to the DUT measurement plane and measurement routines for automated data collection. The second part of the thesis researches black-box frequency-domain behavioral mod- els that can approximate strongly nonlinear, unmatched devices. Our investigation yielded two complimentary solutions to ensure the targeted modelling accuracy. First, improving the accuracy of a first-order expansion-based Poly-Harmonic Distortion (PHD) model by 5dB, in terms of Normalized Mean-Squared Error (NMSE), by minimizing multi-harmonic reflections that artificially increase the order of the nonlinear system. While this addresses the fictitious need for higher-order models due to the deficiencies in the model extraction procedure, strongly nonlinear devices will require high-order models to achieve the targeted accuracy over a larger measurement distribution. Hence, a variable order Multi-Harmonic Volterra (MHV) model is proposed to extend the PHD model formulation to strong non- linear devices. This model is extracted by utilizing the proposed characterization system to extract higher-order multi-variate model coefficients not included in the PHD model. The resulting model improves DC drain current prediction by 5dB and improves funda- mental output-power prediction by 2dB. The MHV model improves the vector power-gain prediction by 3.4dB in realistic PA design applications, thereby providing better emulation of linearization techniques within a simulation environment. Finally, a concurrent dual-band PA design is studied as an example of how the pro- iv posed nonlinear characterization system and behavioural modelling approach can be used to enable complex PA designs. First, a 10W Class-AB PA is designed using dual-band matching-network theory, however it is difficult to implement because the design technique does not control the matching fractional bandwidth as a design parameter. Therefore, an alternative Class-J 45W dual-band PA was designed using a low-impedance matching network, combined with a trans-impedance dual-band filter. Although the dual-band PA can achieve comparable performance to an equivalent single-band PA at each separate fre- quency, further development of characterization, modeling, and circuit design techniques is needed to achieve high-efficiency during concurrent operation.

This book was released on 2022-09-01 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: New Topics in Simulation and Modeling of RF Circuits addresses two main topics: simulation of RF circuits and new models of nonlinear power BAW resonators and filters.Since RF circuits have several unique features, and all analysis methods are based on the circuit essential properties, the book begins by describing the properties of RF circuits, characterization of circuits with customary and uncustomary behavior and some theorems of solutions existence and uniqueness for dynamic nonlinear circuits. Thereafter, the main time domain and frequency domain analysis methods for RF circuits are presented. The advantages and disadvantages of each method have been highlighted, and an algorithm for the time step choice in transient analysis based on energy balance errors is also presented. Lastly, the final part contains some nonlinear circuit models of power BAW resonators. The behavioral models for the time domain analysis are simple circuits containing weakly nonlinear elements. The behavioral models for frequency domain analysis are based on the measured values of the frequency dependent S parameters for a set of incident powers. S parameters corresponding to certain intermodulation products of practical interest are also considered. The physical models contain artificial transmission lines with nonlinear circuit elements corresponding to mechanical and electrical nonlinearities.
