Patent ID: 6980064

Claim:
An electromechanical slide-screw tuner having an input and an output, comprising a transmission line with longitudinal axis, in which a single corrugated slug is moved in, out and along of said transmission line by means of electrical remote control, in such a way as for the physical vertical distance between the said corrugated slug and the center conductor of said transmission line to be remotely adjustable from a maximum of at least two times the diameter of the said center conductor of said transmission line to a minimum distance of zero, said minimum distance corresponding to physical contact between said corrugated slug and said center conductor and in which the physical horizontal position of said corrugated slug is adjustable from a minimum zero to a maximum of one half of a wavelength at the lowest frequency of operation, said corrugated slug having a curved slotted portion in relationship with the transmission line and a corrugation structure comprising at least one slot, said at least one slot being arranged in a direction perpendicular to said longitudinal axis of said transmission line.
