RF and Microwave Circuit Design

In chapter 1, a thorough analysis of RF and microwave concepts and components are presented. Components such as, straight wire, flat ribbon, physical resistors, physical capacitors, and physical inductors are analyzed and their input impedance are simulated.

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 are analyzed. Several transmission line components are modeled and their electrical performance are discussed. Microstrip bias feed and directional couplers are also 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 the first half of Chapter 4, the subject of series and parallel resonant circuits, the effect of load resistance on the bandwidth, the tuning and optimization of the circuit components, and design of the tapped capacitor and inductor are discussed. In the second half of the chapter, design of the lowpass and highpass filters, generation of the physical models, and construction of the filter prototypes are presented. Finally the electromagnetic analysis of the stepped impedance filter, the microstrip edge-coupled bandpass filter design are also treated in this chapter.

In Chapter 5, the conditions for maximum power transfer and the equations for matching any two impedances with are derived. Both analytical and graphical techniques are used to design narrowband and broadband matching networks. In some examples the Impedance Matching Utility in ADS is used to solve any impedance matching problem. Derivation of equations for the Q factor and the number of L-networks, designing with Q curves on the Smith chart, Fano’s limit theorem, and the effect of finite Q on the matching networks are also treated in this chapter.

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. For the broadband case, the cascaded quarter-wave transformer and the single-stub matching networks are used.

In Chapter 7, single-stage amplifiers are designed by utilizing four different impedance matching objectives. The first amplifier is designed for maxim gain where the input and the output are conjugately matched to the source and load impedance; the second amplifier is designed for specific gain where the input or the output is mismatched to achieve a specific gain less than its maximum; the third amplifier is a low noise amplifier where the transistor is selectively mismatched  to achieve a specific Noise Figure; and the fourth amplifier is a power amplifier where the transistor is selectively mismatched to achieve a specific amount of output power. Quarter-wave transformer networks,

In Chapter 8, a two-stage amplifier is designed by utilizing a direct inter-stage matching network. Finally a brief introduction to LNA cascade analysis is presented.
