ABSTRACT:
An amplifier comprises a power source, a load network comprising a load and a resonance circuit, an input branch having a first end electrically coupled to the power source and a second end electrically coupled to the load network, and an active switch having one terminal electrically coupled to the second end of the input branch. The input branch including at least one parallel-LC-circuit configured to provide an infinitely large impedance at harmonics of a determined order.
