Unlike the many traditional textbooks written mainly for the classroom teaching, the High Frequency Circuit Design book can be taught in a classroom or in a computer lab where students can use a very low-cost or no-cost software in solving the many examples in the book. For example, the High Frequency Circuit Design book shows how to use the MATLAB Scripting in solving all the impedance matching examples in the book.This book introduces not only a solid understanding of the RF and microwave concepts and components but more importantly it shows how to use the software tools in the analysis and synthesis of these essential components in a design flow as practiced in industry. A brief organization of the book is as follows:In chapter 1, a thorough analysis of RF and microwave concepts and components are presented.In chapter 2, propagation of the plane waves in different media is introduced. Popular types of transmission lines such as coaxial, microstrip, stripline, and waveguides are defined and their parameters and performances are discussed. Microstrip bias feed and directional couplers are designed. In Chapter 3, derivation of RF and microwave network parameters, development and use of the network S parameters, and the movement of the lumped and distributed elements on the Smith chart are presented. In Chapter 4, the subject of resonant circuits and filters are thoroughly discussed and several resonators and filters are designed. In Chapter 5, the conditions for maximum power transfer and the equations for matching any two impedances are derived. Both analytical and graphical techniques are used to design narrowband and broadband impedance matching networks. In Chapter 6, analytic design equations for quarter-wave transformer and single-stub matching networks are derived. Narrowband and broadband distributed matching networks are designed. In Chapter 7, single-stage amplifiers are designed by utilizing two different impedance matching objectives. The first amplifier is designed for maxim gain where the input and the output are conjugately matched, the second amplifier is a low noise amplifier where the transistor is selectively mismatched to achieve a specific Noise Figure.

A unique, state-of-the-art guide to wireless integrated circuit design. With wireless technology rapidly exploding, there is a growing need for circuit design information specific to wireless applications. Presenting a single-source guidebook to this dynamic area, industry expert Ulrich Rohde and writer David Newkirk provide researchers and engineers with a complete set of modeling, design, and implementation tools for tackling even the newest IC technologies. They emphasize practical design solutions for high-performance devices and circuitry, incorporating ample examples of novel and clever circuits from high-profile companies. They also provide excellent appendices containing working models and CAD-based applications. RF/Microwave Circuit Design for Wireless Applications offers: * Introduction to wireless systems and modulation types * A systematic approach that differentiates between designing for battery-operated devices and base-station design * A comprehensive introduction to semiconductor technologies, from bipolar transistors to CMOS to GaAs MESFETs * Clear guidelines for obtaining the best performance in discrete and integrated amplifier design * Detailed analysis of available mixer circuits applicable to the wireless frequency range * In-depth explanations of oscillator circuits, including microwave oscillators and ceramic-resonator-based oscillators * A thorough evaluation of all components of wireless synthesizers
The modern wireless communication systems require modulated signals with wide modulation bandwidth. This, in turns, requires signals with very high dynamic range and peak-to-average power ratio (PAPR). This means that the amplifier in the base-station has to work at a power back-off as large as the dynamic range of the signal, so that the amplifier has a high linearity in this region. For the standard single-stage amplifiers, this large power back-off reduces the efficiency dramatically. In this work, a three-way Doherty power amplifier (DPA) aiming at high power efficiency within a dynamic range of 9.5 dB, is designed and fabricated using partitioning design approach. The partitioning design approach decomposes a complex design task into small-sized, well-controllable, and verifiable subcircuits. This advanced straight forward method has shown very promising results. Using this design approach, a three-way DPA has been designed to demonstrate the advantages of this reliable design technique as well. Based on the design of a single-stage power amplifier and proposing a novel output power combiner, a 6 W three-way DPA has been designed which allows the mandatory load modulation principle in three-way DPA structures to be realized with simpler elements, whereas the design of a standard Doherty combiner would have been very challenging and not practical due to the extremely small value of its characteristic line impedance. The proposed combiner is calculated for a three-way DPA with 2-mm AlGaN/GaN-HEMTs. The simulation result shows a very good load modulation for the amplifier, which confirms the theoretical expectation for a three-way DPA. The efficiency of the designed 6 W three-way DPA at large back-off shows very promising values compared to recently reported amplifiers. The measured IMD3 products confirm the good linearity of the amplifier as well. Accordingly, the proposed power combiner and the design strategy are recommended to be used as the preferred option for designing three-way DPA structures with very high output power.
