Each block is made using a conductive (aluminum, brass or copper) strip which is mounted vertically on a conductive basis and is wound in spiral form around a center axis. The blocks are guided coaxially into each-other and the relative orientation angle allows approaching the surfaces of the conductive strips from a maximum distance, which is half the width of the spiral gap, to full galvanic contact. The block penetration is motor controlled and a cascade of three or four such capacitors and associated lengths of coaxial cable is used to make wideband impedance tuners operating in the low MHz frequency range.

  • Publication number: 20150009603
    Abstract: A variable vacuum capacitor includes two pairs of electrodes ganged together in series such that no moving parts are required to connect electrically to any static pans. Two sets, or gangs, of movable electrodes are connected mechanically and electrically together such that they move together and such that they require no electrical connection to any other part of the device. The ganged arrangement means that the device can be constructed with a smaller diameter, but without significantly increasing the overall length of the device.

  • Publication number: 20140340814
    Abstract: In a MEMS device, the manner in which the membrane lands over the RF electrode can affect device performance. Bumps or stoppers placed over the RF electrode can be used to control the landing of the membrane and thus, the capacitance of the MEMS device. The shape and location of the bumps or stoppers can be tailored to ensure proper landing of the membrane, even when over-voltage is applied. Additionally, bumps or stoppers may be applied on the membrane itself to control the landing of the membrane on the roof or top electrode of the MEMS device.

  • Patent number: 8891222
    Abstract: A capacitive transducer (1) comprises a polymer film (2) having a first surface and a second surface, a first electrically conductive layer (3) arranged on the first surface of the polymer film (2), and a second electrically conductive layer (3) arranged on the second surface of the polymer film (2). The polymer film (2) is at least partly made from a material having a molecular weight which is at least 21,000 g/mol. The inventors have surprisingly found that silicone polymer materials with high molecular weights, such as liquid silicone rubbers (LSR) or high temperature vulcanizing (HTV) elastomers, have high electrical breakdown strengths, even though technical data sheets from manufacturers state almost identical electrical breakdown strengths similar to that of RTV-2 elastomers. Using such materials in capacitive transducers allows high electrical fields to be applied to transducers without risking electrical breakdown, thereby increasing performance of transducers.
