Abstract
An embodiment of the present invention an apparatus, comprising an adaptive impedance matching module (AIMM) adapted to minimize the magnitude of an input reflection coefficient seen at an RFport under boundary conditions of a variable load impedance Z, a tuner connected to the AIMM and including a plurality of variable reactance networks with independent control signals, wherein node voltages are sampled within the tuner; and a microcontroller or digital signal processor (DSP) calculates complex reflection coefficient information from the sampled voltages, the microcontroller or DSP providing a coarse and fine tune function that feeds bias signals to control impedance matching.
