Claim:
1. A power divider, comprising: a number, N−1, of transmission stages and a number, N−1, of ground layers alternately arranged on respective ones of a plurality, 2(N−1), of dielectric layers, wherein N is an integer greater than 1, wherein a first one of the transmission stages is arranged on a first one of the dielectric layers, wherein the transmission stages are arrayed vertically, each consisting of a loop formed by a transmission line; each of the transmission stages has a respective first opening connected by a respective resistor, and all but the first transmission stages has a respective second opening without a respective resistor; wherein the power divider further comprises a last transmission stage arranged below a last one of the dielectric layers, wherein the last transmission stage is formed by a transmission line having a last first opening connected by a last resistor, and a last second opening without a last resistor, wherein adjacent transmission stages of the N−1 and last transmission stages are connected such that two ends of the first opening of one of the adjacent transmission stages are connected to two ends of the second opening of the other one of the adjacent transmission stages by via transitions, in a top-to-bottom direction; and each of the ground layers has clearances through which the via transitions pass.
