N-way power combiner/divider

Abstract

There is presented herein an N-way power combiner/divider and which includes a common output/input port, a plurality of N input/output ports together with N load ports. N transmission lines interconnect the common output/input port with the N input/output ports. A second plurality of N transmission lines interconnect the respective input/output ports with respective ones of the N load ports. Also, a third plurality of N transmission lines interconnect each of the load ports with a common point and which is, in turn, connected to ground by a capacitor. A first plurality of transmission lines and a second plurality of transmission lines include a plurality of metal foil traces respectively mounted on first and second insulator boards which are spaced from each other. At least three metal layers are provided which are electrically connected together and which serve as ground planes. These layers are spaced from and are parallel to the insulator boards such that the first insulator board is located between the first and second metal layers and the second insulator board is located between second and third metal layers. N electrical connecting pins are provided with each located at one of the N input/output ports. These pins extend between the first and second boards for electrically interconnecting transmission lines on different insulator boards.
