چکیده انگلیسی
A high power solid-state RF power amplifier of 3Â kW at 325Â MHz has been developed using only four RF power amplifier modules of 850Â W power output each. The design and characterization of RF power modules have been presented. A four way Wilkinson power combiner adds the output of four power amplifier modules with a total transmission loss of less than 6%. The combined power amplifier has a power gain of 20.2Â dB at 1-dB compression point, and the corresponding output power is 2.8Â kW at 325Â MHz. The drain efficiency of the power amplifier is 65.3% at 3Â kW. All the harmonics of this amplifier are below â40Â dBc. The amplifier has better characteristics like fewer numbers of active devices per kilo watt, high efficiency, high gain, and ruggedness etc for RF accelerator applications.
