Advanced cavity filter design parasitic bypass couplings Uwe Rosenberg, Walter Hagele - Compensating for ANT Nachrichtentechnik GmbH, Microwave Product Area, Gerberstr 33, D-7150 Backnang, Germany Abstract Higher order mode cavity filters are prone to evident deterioration of the desired ideal responses. The effects accounting for that -namely parasitic bypass couplings - of nonresonating waveg
