This book describes the various devices used in radio communication and broadcasting to achieve high selectivity filtering and coupling.
After providing a background in the basics of microwave theory and more detailed material – including a special chapter on precision and errors in measurement – the reader will find detailed descriptions, manufacturing processes, and, for the most useful instances, a number of worked-through formulas, which will allow engineers and technicians to design circuits or components for filtering or coupling applications. Content is covered in this format across a broad range of fields including coaxial cavities, combline filters, band-pass and pass-reject duplexers, multicouplers, circulators, low-noise amplifiers, helix resonators, and much more.

About the authors

Bernard Piette is a practicing engineer. After working in submarine acoustics, HF electronics, phase-locked loops and telecommunications, he has dedicated his efforts to the design of coaxial cavities and other narrow-band resonators for the last 20 years. He has been a technical manager in several companies specializing in this field, and has designed hundreds of prototypes for numerous French private mobile radio networks such as Radiocom 2000, Rubis and Acropol.
