摘要: A bias circuit is provided for attenuating harmonic distortions of a signal having a simple construction and which can be applied to a high-frequency amplifier used in a communication device, such as a mobile telephone. The circuit reduces a voltage drop therein and thus provides a high-frequency amplifier having reduced power consumption and an increased operating efficiency. The high-frequency amplifier includes an amplifier circuit, an output matching circuit, and the bias circuit. In the bias circuit, a parallel circuit including a first transmission line and a first capacitor has one end connected between the amplifier and the output matching circuit. The other end of the parallel circuit is connected to a power source and is grounded via a second capacitor. In the circuit, the bias circuit can be short-circuited in a desired frequency band while being an open circuit in a frequency band of a signal to be amplified, hence attenuating the harmonic distortions without using a low pass filter.

摘要: A power supply controller includes a power supply section, a power supply controlling section connected to the power supply section, a starter switch being switched selectively to a first status and a second status, a o power switch being switched selectively to a first status and a second status, a controlling section connected to the power switch, and a function section operable to execute a predetermined operation. The power supply controlling section causes a power to be supplied from the power supply section to the controlling section when at least one of the power switch and the starter switch is in the first status. This power supply controller does not malfunction even when the starter switch malfunctions, thus preventing wasteful consumption of the power supply section.

摘要: A transmitter receiver unit of the present invention comprises a phase shifter connected between a transistor and a filter multiplexer for decreasing a reactance component of an impedance, as observed from the transistor toward the filter multiplexer, to a value close to zero in a third frequency band given as the sum or difference between the integer multiples of a second frequency band and a first frequency band. This structure decreases the impedance in the third frequency band of the filter multiplexer side as observed from the transistor, thereby making the transistor not liable to generate a signal voltage of the third frequency band.
