Power amplifiers (PAs) often exhibit instabilities giving rise to frequency divisions or spurious oscillations. The prediction of these instabilities requires a large-signal stability analysis of the circuit. In this paper, oscillations, hysteresis, and chaotic solutions, experimentally encountered in a high-efficiency class-E/F/sub odd/ PA with four transistors combined using a distributed active transformer, are studied through the use of stability and bifurcation analysis tools. The tools… CONTINUE READING
