1. A solid-state direct cavity combiner (DCC) transmitter system for providing megawatts of power, the system comprising:
a resonant cavity including at least one high-power output transmission line;
hundreds of high-power transistors, each transistor generating an amount of power input directly into the resonant cavity;
a plurality of modules, each module including at least one pair of high-power transistors of the hundreds of high-power transistors differentially driving a transmission line and a coupling loop; and
each said transmission line and coupling loop extending into the resonant cavity such as to match an impedance of each said high-power transistor of each said module to an impedance of said resonant cavity to electromagnetically couple power into the resonant cavity to thereby provide the megawatts of power to the at least one high-power output transmission line.
