The present disclosure relates to a tunable waveguide filter arrangement (110) comprising a first filter port (111), a second filter port (112) and a plurality of cavities (113, 114, 115, 116) that are positioned between the first filter port (111) and the second filter port (112). The cavities are electrically interconnected by being arranged in a partly interleaved manner such that overlaps form iris openings (117, 118, 119) between the cavities (113, 114, 115, 116). The tunable waveguide filter arrangement (110) comprises a dielectric element (120, 121, 122, 123) for each cavity (113, 114, 115, 116), extending a certain adjustable protrusion distance (P) along its longitudinal extension (L) from a waveguide top (124) towards a waveguide bottom (125). A longitudinal center (L) of each dielectric element (120, 121, 122, 123) is positioned at a certain closest distance (d1, d2, d3, d4, d5, d6) from at least one adjacent iris opening (117, 118, 119).
A tunable waveguide filter arrangement comprising a first filter port, a second filter port and a plurality of cavities that are positioned between the first filter port and the second filter port and are electrically interconnected by being arranged in a partly interleaved manner such that overlaps form iris openings between the cavities, wherein the tunable waveguide filter arrangement comprises a dielectric element for each cavity, extending a certain adjustable protrusion distance (P) along its longitudinal extension (L) from a waveguide top towards a waveguide bottom, a longitudinal center (L) of each dielectric element being positioned at a certain closest distance from at least one adjacent iris opening.
A method of configuring a tunable waveguide filter arrangement comprising a first filter port, a second filter port and a plurality of cavities that are positioned between the first filter port and the second filter port and are electrically interconnected by being arranged in a partly interleaved manner such that overlaps form iris openings between the cavities, wherein the method comprises
