Document Type and Number:
Japanese Patent JP2898470
Kind Code:
B2
Abstract:
A switched line phase shifter includes at least three transmission lines having different electrical lengths disposed between an input terminal and an output terminal and connectable in parallel to each other, at least three input side FET switches for connecting and disconnecting the input terminal and the input ends of the transmission lines, and at least three output side FET switches for connecting and disconnecting the output terminal and the output ends of the transmission lines. As many signal transmission paths as transmission lines are produced between the input terminal and the output terminal by controlling the input side and the output side FET switches. When one of the signal transmission paths is selected as a reference and a signal is transmitted through the remaining at least two signal transmission paths, at least two different phase shift quantities are obtained in the phase shifter.
