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. |

1. A multi-band RF dielectric monoblock filter for the transmission of an RF signal comprising:
a block of dielectric material including top, bottom, and side exterior surfaces; at least first, second, and third sets of through-holes defining at least first, second, and third sets of resonators and at least first, second, and third RF signal transmission filters, each of the through-holes defining an interior surface and extending through the block of dielectric material and terminating in respective openings in the top and bottom surfaces of the block of dielectric material; a pattern of conductive material on the top, bottom, and side exterior surfaces of the block of dielectric material and the interior surface of the through-holes including respective regions of conductive material on the top exterior surface surrounding the respective openings defined by the at least first, second, and third sets of through-holes respectively; the pattern of conductive material including first, second, and third strips of conductive material defining first, second, and third RF signal input/output transmission lines, the first and second RF signal input/output transmission lines being located at opposite ends of the first and second RF signal transmission filters for the transmission of the RF signal through the first RF signal input/output transmission line, the first and second filters, and the second RF signal input/output transmission line, the second and third RF signal input/output transmission lines being located at opposite ends of the third RF signal transmission filter for the transmission of the RF signal through the second RF signal input/output transmission line, the third RF signal filter, and the third RF signal input/output transmission line. |
