Abstract:
1. A harmonic impedance tuning method (simultaneous synthesis of a set of target impedances at a multitude of harmonic frequencies) for calibrated multi-tuning element impedance tuners comprises the following steps: a) search for an approximate tuning solution (tuner state) at the fundamental frequency (fo), in a coarse calibration grid, b) creation of a fine interpolation grid surrounding the solution found in (a), c) search for tuning solutions at all harmonic frequencies (fo, 2fo, 3fo, . . . ) using the fine grid created in (b), d) select, among the solutions found in (c) the solution with the lowest tuning sensitivity, e) set said tuning elements of said tuner to the solution found in (d).
