Active Radio Frequency Cavity (patent pending, or ARFC) is a concept which enables the integration of a large number of low-power transistors or other solid state devices into a resonant RF cavity, forming a monolithic light-weight, high-efficiency, high-power structure. The low operating voltage of the ARFC (10s of volts to 100+ volts) reduces the costs of high-voltage power supplies and power conditioning equipment. If the cavity is that of a resonant RF particle accelerator, the system is termed an integrated RF power accelerator cavity or IRFPAC. It can be shown that accelerating fields on the order of mv/m can be achieved with state-of-the-art SSDS. Alternately, if the high RF power is piped out of the cavity via wave guide or coaxial cable, the system is then deemed an active RF cavity amplifier, or ARFCA. It is demonstrated that tens of kw of RF power can be obtained at about 80% efficiency at UHF to l-band frequencies.
