Abstract
An actuator for creating linear movement is provided. The actuator includes a motor having a rotatable motor axle. As the rotatable motor axle rotates, it uses internal threads to transfer rotational motion to external threads of a movement axle. By transferring the rotational motion of motor axle to the movement axle, the motor's rotating movement is changed into linear movement. This linear movement can then used for moving a frequency control element such as those used in filters, which are in-turn used in the base station of a cellular radio network.
