摘要: A circuit includes an amplifier to amplify an input signal and generate an output signal. The circuit also includes a tuning network to tune frequency response of the amplifier. The tuning network includes at least one tunable capacitor, which includes at least one micro-electro mechanical system (MEMS) capacitor. The amplifier could include a first die, the at least one MEMS capacitor could include a second die, and the first die and the second die could be integrated in a single package. The at least one MEMS capacitor could include a MEMS superstructure over a control structure, which is to control the MEMS superstructure and tune the capacitance of the at least one MEMS capacitor.

摘要: A magnetoelastically actuated device includes a microscale cantilever arm supported at a standoff distance from a substrate. The cantilever arm is formed as a laminar magnetic actuator configured to bend when it is subjected to a magnetic field. The cantilever arm includes a film of magnetostrictive material. Also provided is a method for fabricating the magnetoelastically actuated device. The method includes defining an actuator mold in a layer of photoresist on a structural layer of the cantilever arm and electrodepositing a layer of a magnetostrictive alloy containing cobalt and iron onto the structural layer within the actuator mold.

摘要: A high power low frequency tuner uses motor controlled rotary capacitors submerged in low loss high epsilon dielectric fluid and lengths of semi-rigid RF cable interconnecting the floating static blocks of the capacitors, the rotating blocks being grounded. And tuner calibration and tuning methods, allowing accurate tuning and perfect Smith chart impedance coverage. The full calibration lasts several hours and is reduced by the “de-embedded” calibration algorithm to minutes. A maximum power embodiment comprises full immersion of capacitors and interconnecting cables in circulated dielectric liquid (mineral oil) for breakdown voltage increase and heat removal.

摘要: The disclosure relates to a compensation capacitor for an antenna of a magnetic resonance scanner and a corresponding antenna with a compensation capacitor. The compensation capacitor has a first electrode and a second electrode arranged in parallel. An insulation material configured to resist high voltages and a dielectric with low dielectric losses are arranged between the first and the second electrode. The second electrode and/or the dielectric may be moved relative to the first electrode such that a surface area of a projection of the surface of the first electrode along the surface normal of the first electrode to the surface of the second electrode and/or the dielectric is variable.
