Abstract
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.
Claims12
A single mode cavity filter, comprising:
- a) at least three rectangular or elliptical resonant cavities and at least four coupling irises aligned along a straight axis, said filter being configured to be tuned by way of an electro-mechanical device in said filter, and
- b) respective tuning rods located in each of said at least three rectangular or elliptical resonant cavities and configured to change the tuning of said filter,
- wherein said tuning rods are aligned along an arcuate axis, and said electro-mechanical device is configured to move the tuning rods according to an identical depth by way of a single motor comprised in said electro-mechanical device.
A method for providing a single mode cavity filter configured to be tuned by an electro-mechanical device in said filter, said method comprising:
- a) providing along a straight axis at least three rectangular or elliptical resonant cavities and at least four coupling irises,
- b) providing along an arcuate axis respective passages located on each respective cavity,
- c) providing tuning rods arranged to be moved according to an identical depth through said respective passages, and
- d) providing an electro-mechanical device configured to move all of the tuning rods by way of a single motor in said electro-mechanical device.
