ABSTRACT: For the first time ever, two or three tuners can be cascaded externally to achieve extremely high magnitudes of reflection (VSWR in the order of 100:1-200:1, £F>0.98) as well as control multiple impedances at multiple frequencies (wideband harmonic tuning). Due to the use of calibrated and interpolated data for all tuners, we are able to achieve an overall system-level accuracy of greater than 40-80dB at highest £F’s.
