Oscillators are an essential part of all spread spectrum, RF, and wireless systems, and todayOCOs engineers in the field need to have a firm grasp on how they are designed. Presenting an easy-to-understand, unified view of the subject, this authoritative resource covers the practical design of high-frequency oscillators with lumped, distributed, dielectric and piezoelectric resonators. Including numerous examples, the book details important linear, nonlinear harmonic balance, transient and noise analysis techniques. Moreover, the book shows you how to apply these techniques to a wide range of oscillators. You gain the knowledge needed to create unique designs that elegantly match your specification needs. Over 360 illustrations and more than 330 equations support key topics throughout the book.
This updated edition of the number one guide to oscillator design presents a unified approach that can be used with a wide range of active devices and resonator types. It includes comprehensive coverage of both linear and nonlinear behavior, as well as CAD synthesis and analysis techniques.
This textbook is an introduction to microwave engineering. The scope of this book extends from topics for a first course in electrical engineering, in which impedances are analyzed using complex numbers, through the introduction of transmission lines that are analyzed using the Smith Chart, and on to graduate level subjects, such as equivalent circuits for obstacles in hollow waveguides, analyzed using Green’s Functions. This book is a virtual encyclopedia of circuit design methods. Despite the complexity, topics are presented in a conversational manner for ease of comprehension. The book is not only an excellent text at the undergraduate and graduate levels, but is as well a detailed reference for the practicing engineer. Consider how well informed an engineer will be who has become familiar with these topics as treated in High Frequency Techniques: (in order of presentation) Brief history of wireless (radio) and the Morse code U.S. Radio Frequency Allocations Introduction to vectors AC analysis and why complex numbers and impedance are used Circuit and antenna reciprocity Decibel measure Maximum power transfer Skin effect Computer simulation and optimization of networks LC matching of one impedance to another Coupled Resonators Uniform transmission lines for propagation VSWR, return Loss and mismatch error The Telegrapher Equations (derived) Phase and Group Velocities The Impedance Transformation Equation for lines (derived) Fano's and Bode's matching limits The Smith Chart (derived) Slotted Line impedance measurement Constant Q circles on the Smith Chart Approximating a transmission line with lumped L's and C's ABCD, Z, Y and Scattering matrix analysis methods for circuits Statistical Design and Yield Analysis of products Electromagnetic Fields Gauss's Law Vector Dot Product, Divergence and Curl Static Potential and Gradient Ampere's Law and Vector Curl Maxwell's Equations and their visualization The Laplacian Rectangular, cylindrical and spherical coordinates Skin Effect The Wave Equation The Helmholtz Equations Plane Propagating Waves Rayleigh Fading Circular (elliptic) Polarization Poynting's Theorem EM fields on Transmission Lines Calculating the impedance of coaxial lines Calculating and visualizing the fields in waveguides Propagation constants and waveguide modes The Taylor Series Expansion Fourier Series and Green's Functions Higher order modes and how to suppress them Vector Potential and Retarded Potentials Wire and aperture antennas Radio propagation and path loss Electromagnetic computer simulation of structures Directional couplers The Rat Race Hybrid Even and Odd Mode Analysis applied to the backward wave coupler Network analyzer impedance and transmission measurements Two-port Scattering Parameters (s matrix) The Hybrid Ring coupler The Wilkinson power divider Filter design: Butterworth, Maximally flat & Tchebyscheff responses Filter Q Diplexer, Bandpass and Elliptic filters Richard's Transformation & Kuroda’s Identities Mumford's transmission line stub filters Transistor Amplifier Design: gain, biasing, stability, and conjugate matching Noise in systems, noise figure of an amplifier cascade Amplifier non-linearity, and spurious free dynamic range Statistical Design and Yield Analysis
Annotation A collection of 16 articles compiled from previously published magazine articles. The articles were selected based on their meeting one or more of three criteria: reviewing important techniques, solving practical problems, or presenting original ideas. Among the specific articles within the broader field of filters and couplers are discussions of matching double-tuned LC filters, microwave multiplexers using complementary filters, RF capacitive-coupled filters, and a new approach to broadband transmission line hybrid design.

Using an accessible yet rigorous approach, Active Filters: Theory and Design highlights the essential role of filters, especially analog active filters, in applications for seismology, brainwave research, speech and hearing studies, and other medical electronics. The book demonstrates how to design filters capable of meeting a given set of specifications. Recognizing that circuit simulation by computer has become an indispensable verification tool both in analysis and in design, the author emphasizes the use of MicroCap for rapid test of the filter. He uses three basic filter types throughout the book: Butterworth, Chenyshev, and Bessel. These three types of filters are implemented with the Sallen-Key, infinite gain multiple feedback, state-variable, and biquad circuits that yield low-pass, high-pass, band-pass, and band-reject circuits. The book illustrates many examples of low-pass, high-pass, band-pass, and notch active filters in complete detail, including frequency normalizing and denormalizing techniques. Design equations in each chapter provide students with a thorough grounding in how to implement designs. This detailed theoretical treatment gives you the tools to teach your students how to master filter design and analysis.
This textbook provides a complete introduction to analog filters for senior undergraduate and graduate students. Coverage includes the synthesis of analog filters and many other filter types including passive filters and filters with distributed elements.
This Special Issue focuses on the state-of-the-art results from the definition and design of filters for low- and high-frequency applications and systems. Different technologies and solutions are commonly adopted for filter definition, from electrical to electromechanical and mechanical solutions, from passive to active devices, and from hybrid to integrated designs. Aspects related to both theoretical and experimental research in filter design, CAD modeling and novel technologies and applications, as well as filter fabrication, characterization and testing, are covered. The proposed research articles deal with different topics as follows: Modeling, design and simulation of filters; Processes and fabrication technologies for filters; Automated characterization and test of filters; Voltage and current mode filters; Integrated and discrete filters; Passive and active filters; Variable filters, characterization and tunability.
