Patent ID: 8405475

Claim:
A microwave impedance tuner having multiple wide-band probes comprising: a tuner having a first tuning probe and at least one other tuning probe, said probes being positionable at a plurality of user selectable positions, said plurality of positions each creating a reflection factor; a processor configured to calibrate the plurality of reflection factors corresponding to each of said plurality of positions of said probes; a memory configured to maintain a database, said database having a plurality of reflection factors corresponding to each of said plurality of positions of said probes; said processor being further configured to segment said database into at least two segments, each of said segments covering an at least partially separate portion of a Smith chart and each of said segments containing an at least partially separate plurality of reflection factors; said processor being further configured to identify a segment in which there is a user selected reflection factor for a first frequency; said processor being further configured to identify a segment in which there is a second reflection factor for a second frequency; said processor being further configured to select a first probe position for a first probe corresponding to said selected first identified reflection factor; said processor being further configured to select a second probe position for a second probe corresponding to said second selected reflection factor; and said processor being further configured to synthesize an impedance by positioning said first probe in said first position and said second probe in said second position.
