Abstract
A radio-frequency system includes an impedance tuning network having a plurality of selectable impedance states and a first port for coupling to a complex load impedance, a detector coupled to a second port of the impedance tuning network and configured to measure scalar values of reflection coefficients at the second port, and a controller configured to, for a first radio-frequency band, sequentially tune the impedance tuning network to at least three different impedance states in each of which the detector measures a scalar value of a corresponding reflection coefficient at the second port, and estimates a value of the complex load impedance based on the scalar values measured by the detector.
