Abstract (en)
[origin: US4734665A] 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.

Bei einem Mikrowellenfilter, bestehend aus mindestens zwei Hohlraumresonatoren (HR1, HR2), in denen jeweils mindestens ein TE- oder TM-Wellenmode existiert, findet eine Kopplung zwischen einem TE-Wellenmode in dem einen der beiden benachbarten Hohlraumresonatoren (HR1, HR2) und einem TM-Wellenmode in dem anderen Hohlraumresonator statt (Fig. 1).
