Claim:
1. A solid state impedance tuner or tuner system operable at RF frequencies, comprising: a first RF port and a second RF port: a control element array configured to have a plurality of solid state control elements turned on simultaneously to achieve a desired impedance state; the impedance tuner or tuner system configured to present impedances to a device under test (DUT) and enable measurement of the DUT's performance as a function of such impedances in a measurement system; and wherein: the control element array comprises N solid state control elements S1 . . . SN, arranged along an RF transmission line and separated from adjacent control elements by transmission line segments; and each control element is controlled by a control line L1 . . . LN; and further comprising: a controller configured to selectively turn on or off each control element by application of a control signal to the corresponding control line to vary an impedance presented by the control element array at the first RF port; the controller configured to selectively turn on a plurality of control elements simultaneously to achieve the desired impedance state.
