  • Patent number: 11404757
    Abstract: A multi-band RF monoblock filter including at least three RF signal filters defined in the monoblock of dielectric material by resonators defined in part by through-holes extending through the block. In one embodiment, two of the RF signal filters are in a co-linear and side-by-side relationship and the third filter is in a parallel and side-by side relationship with one of the two other RF signal filters. A pattern of conductive material defines two end and one interior RF signal input/output on the block top surface. The end RF signal input/outputs are located at opposite ends of the block and the central RF signal input/output is located between the two co-linear and side-by-side RF filters. An RF signal is transmitted through the one end RF signal input/output, the two parallel and side-by-side RF signal filters, and the central RF signal input/output and also through the other end RF signal input/output, one of the co-linear and side-by-side RF filters, and the central RF signal input/output.
