Available in PDF, EPUB and Kindle. Book excerpt: In order to utilise efficiently an allocated frequency spectrum in satellite transponder systems, an accurate channelisation is usually necessary. This can be accomplished by the use of a large number of band-pass filters. These filters are bulky and heavy, and represent a significant percentage of the overall transponder weight. Implementation of more than one mode in a single cavity reduces the volume and weight of the filter. Combination of dual-mode techniques and dielectric resonators will result in a significant reduction of the filter size. l9 This study is devoted to the design of a novel technique for ferrite tuning of dielectric loaded, dual-mode cavity filters, which is dealt with in two specific areas: ....
