摘要： Provided are a direct sampling circuit and a receiver using a discrete time analog process and having a filter effect of a steep attenuation characteristic in a narrow-pass band without lowering a sampling rate. In a discrete time direct sampling circuit (13), the positive phase side and the inverse phase side are both sampled by a local signal for a differential current output of a differential voltage/current conversion unit (1011) and electric charge is accumulated in a charge sampling capacitor. The latest accumulated charge at the positive phase side and charge accumulated at the inverse phase side before a predetermined number of samples are combined with the charge accumulated in a history capacitor (1043) in the past. Thus, it is possible to realize equivalently high-degree FIR filter characteristic.

摘要： When a high power signal is input to an electromechanical device, electrostatic force can automatically and unintentionally drive the movable electrode. A high reliability electromechanical device that prevents this is achieved. The electromechanical device of the invention is an electromechanical device formed on a substrate, and having a signal electrode and a drive electrode formed across a gap from a movable electrode. Applying an attraction force between the movable electrode and the drive electrode enables the movable electrode to contact the signal electrode. A high electrostatic capacitance is formed by disposing the movable electrode and drive electrode in opposition with a dielectric layer therebetween on the RF signal input port side. As a result, the potential difference between the movable electrode and drive electrode is reduced even when a high power signal is input, and a high reliability electromechanical device can be achieved.

摘要： An electromechanical switch includes a first beam, a second beam arranged in parallel with the first beam and connected to the first beam through a connecting portion, a first electrode formed so as to have a first gap with respect to the first beam, a voltage applying portion which applies a voltage between the first beam and the first electrode, and a second electrode formed so as to have a second gap with respect to the second beam. The second gap is greater than the first gap. The first beam is displaced when the voltage applying portion applies the voltage between the first beam and the first electrode, so that switching between the second beam and the second electrode is performed in a state that the first beam is not electrically connected to the first electrode.

摘要： A switch comprises voltage applying means for providing direct current potentials to first to third beams arranged with a spacing slightly distant one from another, and electrodes for inputting/outputting signals to/from the beams. By controlling the direct current potential provided to the beam, an electrostatic force is caused to thereby change the beam positions and change a capacitance between the beams. By causing an electrostatic force between the first and second beams and moving the both beams, the first and second beams can be electrically coupled together at high speed. Also, an electrostatic force is caused on the third beam arranged facing to the first and second beams, to previously place it close to the first and second beams. When the electrostatic force is released from between the first and second beams, the second beam moves toward the third beam thereby releasing the first and second beams of an electric coupling.

First and second major-surface terminal electrodes are arranged on a major surface of the capacitor body. First and second internal electrodes which are opposed to each other within the capacitor body are respectively electrically connected at ends thereof to the first and second side-surface terminal electrodes, and are also respectively electrically connected to the first and second major-surface terminal electrodes through via hole conductors.
