  • Direct cavity combiner (DCC) for combining hundreds of high-power transistors into a transmitter system for providing megawatts of power
    Patent number: 12381303
    Abstract: A solid-state direct cavity combiner (DCC) transmitter system for providing megawatts of power is featured. The system includes a resonant cavity including at least one high-power output transmission line, hundreds of high-power transistors each generating an amount of RF power input directly into the resonant cavity, and a plurality of modules each including at least one pair of high-power transistors differentially driving a transmission line and a coupling loop. Each said transmission line and coupling loop extends into the resonant cavity to match an impedance of each said high-power transistors of each said module to an impedance of said resonant cavity to electromagnetically couple power into the resonant cavity to provide the megawatts of power to the high-power output transmission line.
