Cripps, Stephen Charles ORCID:, Tasker, Paul ORCID:, Clarke, A. L., Lees, Jonathan ORCID: and Benedikt, Johannes ORCID: 2009. On the continuity of high efficiency modes in linear RF power amplifiers. IEEE Microwave and Wireless Components Letters 19 (10) , pp. 665-667. 10.1109/LMWC.2009.2029754

A novel formulation for the voltage waveforms in high efficiency linear power amplifiers is described. This formulation demonstrates that a constant optimum efficiency and output power can be obtained over a continuum of solutions by utilizing appropriate harmonic reactive impedance terminations. A specific example is confirmed experimentally. This new formulation has some important implications for the possibility of realizing broadband >10% high efficiency linear RF power amplifiers.
