وصف كتب مصر
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.
