    Abstract: The present invention discloses a distributed power amplifier topology and device that efficiently and economically enhances the power output of an RF signal to be amplified. The power amplifier comprises a plurality of push-pull amplifiers interconnected in a novel circular geometry that preferably function as a first winding of an active transformer having signal inputs of adjacent amplification devices driven with an input signal of equal magnitude and opposite phase. The topology also discloses the use of a secondary winding that matches the geometry of primary winding and variations thereof that serve to efficiently combine the power of the individual power amplifiers. The novel architecture enables the design of low-cost, fully-integrated, high-power amplifiers in the RF, microwave, and millimeter-wave frequencies.

    Abstract: A capacitor has a capacitor element, an electrolyte, a cylindrical case made of metal and having a bottom, a metal terminal plate, and a sealing rubber. The terminal plate has a body portion and a flange portion projected from an outer peripheral surface of the body portion toward the case. The sealing rubber is abutted onto the flange portion of the terminal plate, and is interposed between the outer peripheral surface of the body portion of the terminal plate and a side surface of the case for sealing the case. The case has a drawn and grooved portion formed by being drawn and thus grooved from an outside of the side surface at a place so that the sealing rubber is compressed between the outer peripheral surface of the body portion of the terminal plate and the case. Then, a ring-like groove is provided on the outer peripheral surface of the body portion of the terminal plate at a portion, which is padded with the sealing rubber, the sealing rubber is projected into the groove.

    Abstract: A capacitor includes a capacitor element including first and second electrodes, an electrolyte solution, first and second collector plates made of metal and joined to the first and second electrodes of the capacitor element, respectively, a case accommodating the capacitor element, the electrolyte solution, the first and second collector plates, a terminal plate placed at an opening of the case and joined to the second collector plate, and a sealing rubber sealing the terminal plate and the opening of the case. The case has a tubular portion and a bottom plate closing the tubular portion. An inner surface of the bottom plate of the case has a contacting portion contacting the first collector plate and a junction portion facing the first collector plate. The first junction portion of the inner surface of the bottom plate has a joining point joined to the first collector plate and a separation part facing the first collector plate around the first joining point by a first gap between the first junction portion and the first collector plate. The first collector plate is located away from the first contacting portion. The capacitor has a high reliability in connecting the electrodes, preventing an unnecessary resistance or a pin hole produced in the case.

    Abstract: A cross-differential amplifier is provided. The cross-differential amplifier includes an inductor connected to a direct current power source at a first terminal. A first and second switch, such as transistors, are connected to the inductor at a second terminal. A first and second amplifier are connected at their supply terminals to the first and second switch. The first and second switches are operated to commutate the inductor between the amplifiers so as to provide an amplified signal while limiting the ripple voltage on the inductor and thus limiting the maximum voltage imposed across the amplifiers and switches.
