The present invention provides an apparatus and a method of fabricating the apparatus. A radio frequency feed receives RF signals and at least one MMIC is operatively connected to the RF feed and receives the RF signals from the RF feed. The control element has two links that are connected to one another in the manner of a toggle lever by means of a toggle joint. A protective cover surrounds the tensile-strength layer and has an outside diameter DO in the range 3 mm\u2266DO\u22665 mm.
