Abstract: A tuning device for an RF cavity or RF antenna has an actuator (7) mechanically coupled (8) to a tuning element (14), such as a tuning pin of an RF cavity. The actuator is an SMA-wire actuator capable of linear movement connected via a mechanical link to an RF tuning pin such that the tuning pin is moveable by the actuator in and out of the RF-cavity. The actuator may comprise a straight SMA wire or a bowstring SMA wire coupled to a return spring, or it may be an SMA-wire actuator comprising a pair of opposed bowstring-actuators (1,2) eliminating the requirement for a return spring and with a design methodology that allows a wide range of performance specifications and envelope sizes.
