摘要： The present invention relates to a device at filters for filtering unwanted signals from radio transmitters and/or for use during combination of radio transmitters. Said filter (1) has at least one cavity (2 and/or 3) for filtering radio signals. At least one compensating means (13 and/or 16) is provided to compensate for deviations in frequency depending on expansion or contraction of the cavity (2 and/or 3) due to expansion or contraction of the filter (1) when said filter is heated or cooled during operation. The filter (1) has at least one cavity (2 and/or 3) which is designed for simultaneous filtering of radio signals of at least three different modes (A, B and C and/or D, E and F) and the same frequency. The compensating means (13 and/or 16) is provided in said cavity (2 and/or 3) for compensating deviations in frequency by simultaneously affecting the radio signals of the at least three different modes (A, B and C and/or D, E and F).

摘要： An externally temperature-compensated microwave resonator comprises a microwave resonator and an external temperature compensator. The microwave resonator is a multi-cavity waveguide. The cavities are configured side-by-side and coupled through irises. The external temperature compensator is oriented and configured to effect a change in volume of the cavities when the resonator and compensator undergo a temperature gradient. The compensator deflects a wall portion of the resonator to accordingly counteract a change in volume of the cavity caused by a temperature gradient.
