Microwave and radiofrequency (RF) circuits play an important role in communication systems. Due to the proliferation of radar, satellite, and mobile wireless systems, there is a need for design methods that can satisfy the ever increasing demand for accuracy, reliability, and fast development times.This book explores the principal elements for receiving and emitting signals between Earth stations, satellites, and RF (mobile phones) in four parts.
The first part is entirely devoted to the theory and realization of couplers, starting with a recap of fundamental knowledge about microwave coupled lines, defining in particular the even and odd modes, then moving on to applications in microwave systems and challenges that can arise within the system.
The second part explores how to compute and realize microwave and RF filters, investigating the design of different filters by looking at synthesis theory and methods.In the third part, microwave and RF amplifiers are discussed, specifically throughexamples ofdifferent flow graphs, the limits of stability, and noise as a problematic factor in amplifiers, among other topics.
The final part explores microwave and RF oscillators, discussing quasi-static analysis, overvoltage coefficients and extension into non-linear circuits, but also synchronization and the realization of stable oscillators.
