Abstract: An in-line resonator filter (400) comprising a linear array of three or more conductors (410), the linear array comprising: a first pair of adjacent conductors (410(1), 410(2)) having inductive main coupling and oppositely signed capacitive main coupling; a second pair of non-adjacent conductors (410(1), 410(3)) having inductive cross-coupling; and one or more tuning elements (422), each extending from a ground plane of the in-line resonator filter, wherein: the first and second pairs have one conductor (410(1)) in common; between the second pair of non-adjacent conductors, there is no direct ohmic connection that provides the corresponding inductive cross-coupling; and at least a portion of the oppositely signed capacitive main coupling compensates for at least a portion of the inductive main coupling between the first pair of adjacent conductors.
