ABSTRACT:
A novel arrangement to achieve high power amplification of a microwave signal by summing the contributions of many small power amplifiers. This arrangement comprises the equivalent of a divider network to distribute an incoming signal to an arbitrary number of small power amplifiers, and a combiner to sum the outputs of all amplifiers into a single output. This arrangement combines the series-fed circuit concept with a dual mode transmission media (a transmission line capable of transmitting two independent orthogonal modes, for example, the circular waveguide TE.sub.11 mode) for the divider and combiner.
