Abstract (en)
[origin: EP0443481A1] Ferrite-tuneable agile microwave filter. <??>It is built as a filter with resonators with dielectric confinement, and therefore comprises an evanescent-mode guide (2) and resonant cylinders (15, 16) placed in this guide. Furthermore, means (11A, 11B, 17) are provided for applying an adjustable magnetic field (H1, H2) to these cylinders (15, 16), which have the feature of being made of ferrite, in order to shift the central frequency of this filter. <IMAGE>
