ABSTRACT:
A microwave power combiner is formed in a cylindrical hollow metallic housing utilizing a number of pie shaped chambers formed with metallic vanes attached to and extending radially inward from the interior sidewalls of the cylindrical hollow metallic housing. Individual microwave power sources exterior to the cylindrical hollow metallic housing transmit energy into the pie shaped chambers. Two ring shaped metallic vane straps are used to control impedance mismatches and the resonant frequency of the microwave power combiner. The microwave power from the individual microwave power sources combine in the cylindrical hollow metallic housing and is extracted through the circular top of the cylindrical hollow metallic housing by means of a waveguide or a transmission line. The individual microwave power sources can be replaced as needed without affecting impedance matching or the efficiency of power transfer. There is flexibility in the number of individual microwave power sources used.
