Abstract
A microwave filter composed of at least two cavity resonators disposed adjacent one another, and a coupling aperture disposed between the resonators for coupling microwave energy between the resonators, one of the cavity resonators being operative to propagate microwave energy having a TE mode and the other of the cavity resonators being operative to propagate microwave energy having a TM mode, wherein the coupling aperture is constructed for coupling the TE mode in the one cavity resonator with the TM mode in the other cavity resonator.
Claims4
In a microwave filter comprising at least two cavity resonators disposed adjacent one another, and means including a coupling aperture disposed between said resonators for coupling microwave energy between said resonators, one of said cavity resonators constituting means for propagating microwave energy having a TE mode and the other of said cavity resonators constituting means for propagating microwave energy having a TM mode, the improvement wherein said means including a coupling aperture are constructed for coupling the TE mode in said one cavity resonator with the TM mode in said other cavity resonator.
