1. A power source module, comprising:
a heat sink having a surface oriented in an X-Y plane; an RF input; a 1:L port split-block waveguide splitter having an input waveguide coupled to the RF input and L output waveguides in the X-Y plane, said splitter having a bottom portion formed in the surface of the heat sink and a top portion; L solid-state amplifier chips on the surface of the heat sink, each chip having an input and an output; a first L chip-to-waveguide end-launched transitions configured to couple the L output waveguides to the inputs of the L solid-state amplifier chips, respectively, each said transition configured to overhang into the corresponding output waveguide for an end launch coupling of the output waveguide to the input of the corresponding chip parallel to that chip in the X-Y plane; a second L chip-to-waveguide end-launched transitions configured for an end launch coupling of the outputs of the L solid-state amplifier chips, respectively; and an output radiator waveguide array having L radiator input waveguides coupled to the second L chip-to-waveguide end-launched transitions, respectively, in the X-Y plane, each of said second L chip-to-waveguide launched transitions configured to overhang into the corresponding radiator input waveguide for an end launch coupling of the output of the corresponding chip into the radiator input waveguide parallel to that chip, each of said L radiator input waveguides coupled to M×N free-space radiating elements in a two-dimensional aperture in the X-Z plane. |
