Beskrivning

Waveguide Junction Circulators brings together for the first time all the design aspects of this class of device. In a typical application the circulator allows a single antenna to be used for both transmission and reception. Together with semiconductor, passive and electronic devices, the circulator constitutes an essential building block in modern radar, satellite and telecommunication equipment. Features include:* Examination of the properties and adjustments of the 3-port junction circulator and focus on the gyromagnetic resonator* Description of the design of practical classic circulator arrangements* Discussion of aspects of filter theory in the design of the classic 3-port junction circulator* Consideration of practical concerns such as insertion loss and commercial specificationsWritten by a leading academic authority and experienced industrial consultant, Waveguide Junction Circulators is a vital information source for designers working in microwave engineering. This valuable guide provides the academic researcher with a firm foundation in the theoretical aspects of this class of device whilst offering the industrial engineer an experimental platform for commercial design.
