Includes bibliographical references and index Reminders and general points -- Measurements in HF -- Resonant cavities -- Fabrication and tuning of cavities -- The band-pass filter -- The combline filter -- Channel multiplexing -- Auxiliary devices -- Directive couplers -- Helical resonators -- Multicouplers -- Utilities -- Various questions and exploratory ways 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 Radio filters Directional couplers 0 0 0 0 20000 20000 2019-09-04 450.15 0 TK6565.F5 P54 2010 0000061268 2019-09-04 00:00:00 1 450.15 2019-09-04 OPEN VIRTUA40 57370 57376 VTLSSORT0080*0200*0201*0400*0410*0900*1000*2400*2450*2600*3000*5040*5050*5200*6500*6501*9991
