摘要： A multiple power mode amplifier includes: N amplifiers connected in series via switches; and a control circuit for controlling the N amplifiers in accordance with the output modes. P amplifiers out of the N amplifiers constitute a driver amplifier, and constitute a negative feedback amplifier including a feedback circuit for negatively feeding back its own output signal to its own input side. N−P amplifiers constitute a final stage amplifier connected in series to the negative feedback amplifier in a disconnectable manner. The control circuit is configured to: in a first output mode, disconnect the final stage amplifier from the negative feedback amplifier, and disable the feedback circuit; and in a second output mode, connect the final stage amplifier in series to the negative feedback amplifier, and enable the feedback circuit.

摘要： While minimizing any increase in chip size and without incurring a loss in performance or operating characteristic under normal operating voltage conditions, a power amplifier protection circuit effectively prevents breakdown of power amplifying transistors resulting from output load fluctuations during operation with an overvoltage supply. The protection circuit includes a gate circuit electrically connected between the collector and base of at least the last-stage transistor in a power amplifier including transistors connected in stages. The gate circuit passes a feedback current to the base electrode of the protected transistor when a voltage exceeding a specific level is applied to the collector of the protected transistor.

摘要： A mobile terminal displays a screen image provided by an image data which is produced. An in-vehicle apparatus is fixed to a vehicle or is mounted on the vehicle to be portable. The mobile terminal sends the image data to the in-vehicle apparatus through communication such that a vehicle display portion of the in-vehicle apparatus displays a screen image provided by the image data. In a case where a communication between the in-vehicle apparatus and the mobile terminal is established, when one of the mobile terminal or the in-vehicle apparatus, in which an input operation has been performed prior to the other of the mobile terminal or the in-vehicle apparatus, is in operation, only the one of the mobile terminal or the in-vehicle apparatus is operable.

Antenna elements having transmission modules, respectively, are arranged in plurality, wherein the plurality of transmission modules respectively have transmission signal generators that each output a transmission intermediate frequency signal, local oscillation signal generators that each output a local oscillation signal, and transmission mixers that each mix the transmission intermediate frequency signal and the local oscillation signal with each other, thereby to carry out frequency conversion to a transmission high frequency signal. A reference signal source inputs a reference signal to the transmission signal generators and the local oscillation signal generators. The transmission intermediate frequency signal and the local oscillation signal are synchronized with each other by the reference signal.
