ABSTRACT:
An RF switch is provided. In the RF switch, a slot line is divided into a first slot line and a second slot line and an open-end circuit is provided at each end portion of the first and second slot lines. A first transmission line delivers signals from and to the first slot line, and a second transmission line delivers signals from and to the second slot line. A third transmission line delivers signals from and to the portion of the slot line that separates the first slot line from the second slot line. A variable sub open-end circuit portion includes at least one open-end circuit which is selectively switched to the first or second slot line according to an external switching control signal.
