RF filter structures are disclosed that may have multiple filter paths, which are provided by weakly coupled resonators. The filter paths may be interconnected so that additional filter paths may be realized between input and output terminals of the RF filter structures. The weakly coupled resonators from the filter paths may be arranged in a matrix. In one embodiment, an RF filter structure includes a first filter path and a second filter path. The first filter path includes (at least) a first pair of weakly coupled resonators while a second filter path includes (at least) a second pair of weakly coupled resonators. To interconnect the first filter path and the second filter path, a cross-coupling capacitive structure is electrically connected between the first filter path and the second filter path. As such, an additional filtering path may be realized through the interconnection provided by the cross-coupling capacitive structure.
