Abstract
A power combiner including a plurality of phasing transmission lines (122) supporting a set of amplifiers (103-105) coupled thereto, and a plurality of matching transmission lines (123-124). The set of amplifiers (103-105) have a selectable number of amplifiers between a minimum and a maximum value having gain levels between a minimum and a maximum value. Each of the matching transmission lines (123-124) is coupled to one of the phasing transmission lines (122) at one end and coupled to a common node (126) at the other end. Each of the matching transmission (123-124) lines has a characteristic impedance determined according to a function of the minimum and the maximum number of amplifiers in the set of amplifiers (103-105) and the minimum and maximum gain levels in the set of amplifiers (103-105).
