摘要： A single mode cavity filter having at least three rectangular or elliptical resonant cavities and at least four coupling irises aligned along a straight axis is disclosed. The filter is configured to be tuned by way of an electro-mechanical device. The filter has tuning rods located in each of the cavities and configured to change, in use, the tuning of the filter. The tuning rods are aligned along an arcuate axis and the electro-mechanical device is configured to move the tuning rods according to an identical depth by way of a single motor in the electro-mechanical device.

摘要： A dual mode cavity filter installed aboard a satellite having a first and a second waveguide cavity, a first coupling waveguide iris having an input slot and followed by the first waveguide cavity, a second coupling waveguide iris having a coupling slot, following the first waveguide cavity and followed by the second waveguide cavity, and a third coupling waveguide iris having an output slot and following the second waveguide cavity. The dual mode cavity filter is associated with a plurality of devices having at least one respective commanded rod having a certain insertion length with respect of the waveguide cavities and of the slots. The devices are placed in predetermined positions of the cavities and/or of the irises and are arranged to perform a tuning modification and/or a coupling modification of the filter by controlling the insertion length of the rods in outer space.
