Abstract :
This paper presents a novel direct calculation method for matching network dynamic control utilizing an analytic algorithm based on an integrated measurement of load impedance. In principle, this approach has no limitations on the match tuned load impedance and the operating frequency, but in practice its operation is restricted by the matching network tolerances and the accuracy and dynamic range of the load impedance measurement circuitry. The matching network consisting of MEMS tunable capacitors and high Q fixed inductors is one of the best choices for this loop since it has a broad match tuning range across loads condition and frequencies.
