摘要： An amplifier circuit is configured in such a manner that the withstand voltage between the terminals of a FET 2 (withstand voltage B) is higher than the withstand voltage between the terminals of a FET 1 (withstand voltage A), and that the gate width of the FET 1 (Wg1) is narrower than the gate width of the FET 2 (Wg2). This makes it possible to increase the gain while maintaining high output power. The narrow gate width of the FET 1 (Wg1) connected to an input terminal 3 enables reducing the size of the cascode amplifier.

摘要： A high-frequency amplifier module includes a driver-stage amplifier 3 that amplifies an RF signal input thereto from an RF input terminal 1, and a final-stage amplifier 5 that amplifies the signal amplified by the driver-stage amplifier 3 and outputs the signal after the amplification to an RF output terminal 7. The driver-stage amplifier 3 is fabricated on a silicon substrate 11, while the final-stage amplifier 5 is fabricated on a gallium arsenide substrate. This configuration downsizes the cost while maintaining a high-frequency characteristic comparable to that in the case where all components of an entire module are fabricated on a gallium arsenide substrate 71.

摘要： An image formation apparatus includes an image reading control unit and a print control unit. The print control unit includes: a first communication control unit connected to the image reading control unit; and a power supply control unit configured to control power supply to the image reading control unit. The image reading control unit includes: a second communication control unit connected to the first communication control unit. When completing a process to transition to a power save mode in accordance with an instruction from the print control unit, the image reading control unit cuts off the communications through the second communication control unit. After sending the image reading control unit the instruction to transition to the power save mode, the print control unit detects the cutoff of the communications and then cuts off the power supply to the image reading control unit through the power supply control unit.

摘要： A detector circuit for detecting degradation in the distortion characteristics of a power amplifier based on signals from both ends of a coupled line of a directional coupler. The detector circuit includes a phase shifter/attenuator for phase shifting and attenuating a signal from a coupled terminal of the coupled line, a differential amplifier for outputting difference between an output signal from the phase shifter/attenuator and a signal from the isolated terminal of the coupled line, a wave detector circuit for converting the difference into a DC signal, and a comparing circuit for determining whether the voltage level of the DC signal exceeds a predetermined level. When degradation in the distortion characteristics of the power amplifier arises, the phase shifter/attenuator phase shifts the signal from the coupled terminal and outputs a signal 180° out of phase with the signal from the isolated terminal.
