Abstract
This paper describes a novel simple, however highly versatile harmonic source-pull/load-pull approach for high-power applications in the kilowatt range at frequencies of up to 500MHz. The proposed concept eliminates almost all frequency selective components by removing all filters except the bias tees, hereby enabling very quick changes of the opera-ting frequency in the range of more than two decades.
