摘要： A distributor distributes an input signal to a first transmission line and a second transmission line. A high-pass filter, a first linearizer, and a first phase shifter disposed on the first transmission line adjust the phase and amplitude of an intermodulation distortion in a low-frequency range. A low-pass filter, a second linearizer, and a second phase shifter disposed on the second transmission line adjust the phase and amplitude of an intermodulation distortion in a high-frequency range. A synthesizer synthesizes the signal from the first transmission line and the signal from the second transmission line.

摘要： A dielectric heating device is provided with two or more electrodes, a grounded surface connected to a first electrode, a signal source connected to a second electrode to output a high-frequency signal, a first element interposed serially between the signal source and second electrode, and a second element interposed serially between the grounded surface and first electrode. The first element includes two terminals that electrically connect the signal source and second electrode in a non-contact manner, to cause the high-frequency signal outputted from the signal source to pass through the first element, by using the electric coupling between the two terminals. The second element includes two terminals that electrically connect the grounded surface and first electrode in a non-contact manner, to output, by using the electric coupling between the two terminals, the high-frequency signal outputted from the signal source, to the grounded surface.

摘要： A power amplifier is smaller in size and limits input noise having a differential frequency. A power amplifier has an input terminal, an amplifying transistor, a bias circuit, a filter circuit, and an impedance matching circuit. The bias circuit supplies a bias to the signal input side of the amplifying transistor. The filter circuit removes noise at the signal input side of the amplifying transistor. The filter circuit has a matching resistor, a chip inductor, and a chip capacitor. Each of the chip inductor and the chip capacitor is a surface mount device. The matching resistor is located on a semiconductor substrate, has a first end connected to a connection point of two MIM capacitors, and a second end connected to a connection point of one of the MIM capacitors and the signal input side of the amplifying transistor.
