Abstract
A solid state impedance tuner or impedance tuner system includes a control element array with a plurality of solid state control elements configured to be turned on simultaneously to achieve a desired impedance state. The control element array comprises N solid state control elements arranged along an RF transmission line. A controller selectively turns on or off each control element by application of a control signal to vary an impedance presented by the control element array, Another aspect is an impedance tuner module card configured in a standardized system architecture, with a chassis board, and at least one solid state tuner module integrated on the card A chassis electrical connector connected to the tuner module is configured for connection to a corresponding backplane connector. Methods for calibrating a solid state impedance tuner that includes at least two solid state tuner modules combined in one package are disclosed.
