摘要： In accordance with an embodiment, a system includes a first amplifier and a first bandpass filter having an input coupled in series with an output of the first amplifier, and an output configured to be coupled to a load. The bandpass filter has a lower input impedance at an in-band center frequency than at out-of-band frequencies, and the first amplifier is configured to receive a pulse width modulated waveform filtered according to a first transfer function that attenuates sidebands of the pulse width modulated waveform.

摘要： In an embodiment, a method of producing a multi-level RF signal includes producing plurality of pulse-width modulated signals based on an input signal. The method further includes driving a corresponding plurality of parallel amplifiers with the plurality of pulse-width modulated signals by setting a parallel amplifier to have a first output impedance when a corresponding pulse-width modulated signal is in an active state and setting the parallel amplifier to have a second output impedance when the corresponding pulse-width is in an inactive state. The method also includes phase shifting the outputs of the plurality of parallel amplifiers, wherein phase shifting transforms the second output impedance into a third impedance that is higher than the second output impedance, and combining the phase shifted outputs.

摘要： A variable resistor of modular design having a hub-flange and at least one housing frame having a central opening. A spring carrier provided with a contact spring is arranged in the central opening of the housing and is rotatable by means of an actuation shaft. A carrier plate, on which the resistor course and the collector course are mounted, is positioned adjacent the spring carrier such that the contact spring provides an electrical connection between the resistance and the collector courses. The housing frame has a pot-shaped front side for receiving a rotor. Means is provided for arresting rotation of the rotor to within predetermined angular limits, and the rotor has a contoured rim for engaging a click-stop device.

摘要： A variable electromechanical device, such as a rotary potentiometer, incls a housing with a sleeve having a bore through which an actuation shaft extends. The shaft is provided with an annular groove. A portion of the sleeve is displaced by stamping so that it extends into the annular groove of the shaft to prevent axial movement of the latter. A projection formed on the shaft within the annular groove cooperates with the displaced portion of the sleeve for limiting the rotation of the shaft. A lubricating and braking liquid of high viscosity is filled in the groove, and one or more passages are formed on the projection so that the liquid can pass from one side of the projection to the other side thereof when the shaft is rotated.
