Multi octave frequency-range electro-mechanical impedance tuners cover frequencies from the megahertz (FM range) to the high (millimeter-wave) gigahertz range, by combining a high frequency with one or two low frequency slide screw tuner modules. Special configurations allow for compact size. The low frequency module can be bypassed using SPDT remotely controlled millimeter wave switches. Appropriate calibration, control and tuning procedures allow for a fully integrated operation.
