N-WAY COAXIAL WAVEGUIDE POWER DIVIDER/COMBINER

摘要

A low loss and compact power divider/combiner is provided for high power efficiency. The power divider/combiner can be an N-way coaxial-waveguide cavity power divider/combiner with good characteristics of low loss and compact size. The power divider/combiner can be comprised of a coaxial common port, a radial-waveguide cavity, and N-way probe outputs. In various embodiments, the power divider/combiner can have a plurality of probe outputs that are equally spaced radially around an axis on which the coaxial common port is located. The radial-waveguide cavity and N-way probe outputs can be fabricated on a substrate board using printed circuit technology. In addition, the power divider/combiner can have reversed probe outputs which provide for 180 degree out of phase outputs between the probe outputs.
