An improved variable matching network for use in a multi-band, multi-mode communications device provides dynamic, fine-tune impedance matching based on current operational conditions associated with a given signal. In one embodiment, gross parameters are selected based on one or more of the operational conditions. Delta parameters are provided using an optimization algorithm based on one or more of the operational conditions. And the gross and delta parameters are combined to obtain overall matching parameters that dynamically fine-tune discrete matching circuitry.
