    • When generating an RF test signal for mismatch calibration for receiver in order to calibrate reception mismatch of an I-phase signal and a Q-phase signal that are output from demodulated signal processing circuits coupled to mixers for receiving, a Tx VCO avoids covering the higher frequency of an RF received signal in an FDD system. An RF test signal generating unit generates, in a calibration mode of a mismatch calibration for receiver circuit, the RF test signal by using an oscillation output signal of the Tx VCO and other circuits, and supplies the same to the mixers for receiving via a switch. The RF test signal has a frequency within an RF reception frequency band that is higher than that of an RF transmission signal with the maximum frequency band of multiband radio frequency communications. By switching the switch in a reception mode, an output of a low-noise amplifier that amplifies the RF received signal received by an antenna is supplied to each of the mixers for receiving.
    • 为了校准从耦合到混频器进行接收的解调信号处理电路输出的I相信号和Q相信号的接收不匹配,为接收机生成用于失配校准的RF测试信号时,Tx VCO避免覆盖较高的 FDD系统中RF接收信号的频率。 RF测试信号产生单元通过使用Tx VCO和其它电路的振荡输出信号在接收机电路的不匹配校准的校准模式中产生RF测试信号,并将其提供给用于经由开关接收的混频器 。 RF测试信号具有比具有多频带无线电频率通信的最大频带的RF传输信号的RF接收频带内的频率。 通过在接收模式下切换开关,将放大天线接收到的RF接收信号的低噪声放大器的输出提供给每个混频器进行接收。

    • A malfunction determination device for a motor control system, outputs a position signal that indicates a moved position of a movable member of a motor and a direction signal that indicates a movement direction of the movable member. The malfunction determination device determines a malfunction has occurred if a relationship between the position signal and the direction signal differs from that when the motor control system is operating normally. The malfunction determination device outputs a pulse signal that varies periodically along with variations in the moved position of the movable member as the position signal; outputs a periodic pulse signal in the same phase with the position signal as the direction signal if the movable member is moving in one direction; and outputs a periodic pulse signal in an opposite phase to the position signal as the direction signal if the movable member is moving in the other direction.
