ABSTRACT:
A solid state power amplifier which combines the output of several power modules by means of a waveguide radial combiner. The physical structure of the amplifier is such that the power modules lay flat on a planar heat sink which can be easily cooled by forced air. The input power can be distributed to the power modules by means of a microstrip divider. The divider can be connected to the modules by means of coaxial cables and the modules can be connected to the radial combiner by means of microstrip to waveguide transitions.
