  • Tuneable ultra-high frequency filter with mode TM010 dielectric resonators
    Patent number: 4578655
    Abstract: A filter comprising a metal case having a metal base and a lid forming a guide of any section but under cut-off, that is to say which does not allow guided propagation. Cylindrical dielectric resonators are in contact with the metal securing base and the resonators resonate then in the TM010 mode. For frequency tuning of the filter, the distance between the bottom of the lid and the ends of the dielectric resonators supported by the base is variable. The invention applies more especially to tuneable band-pass filters.
