Vacuum sealing radio frequency (rf) and low frequency conducting actuator

A high frequency linear actuator, comprising:

• an actuator body having a first portion and a second portion, each arranged along a longitudinal axis of the actuator body;
• a vacuum bellows concentrically located in the first portion of the actuator body, the vacuum bellows being configured to seal a vacuum environment communicated within the vacuum bellows from the second portion of the actuator body;
• a linear motion shaft concentrically located substantially within the actuator body and configured to move in a linear direction along the longitudinal axis of the actuator body, an electrically conductive portion of the linear motion shaft being configured to receive and conduct a high frequency signal, the electrically conductive portion concentrically located substantially within the vacuum bellows and electrically insulated from the vacuum bellows, a lift force generating portion of the linear motion shaft being concentrically located substantially within the second portion of the actuator body;
• a radio frequency connection bar electrically coupled to the electrically conductive portion of the linear motion shaft, the radio frequency connection bar configured to be electrically coupled to an external radio frequency energy source;
• and
• an electrical contact pad in electrical communication with the electrically conductive portion of the linear motion shaft and configured to electrically couple to another surface upon activation of the linear motion shaft.
