    • A transceiver includes an oscillator and a plurality of communication blocks. Each of the communication blocks includes frequency dividers and mixers. Frequency dividing number of the frequency divider included in one communication block is set to an even-numbered integer, and transmission local signals supplied from the frequency dividers to the mixer become quadrature signals having a phase difference of 90 degrees. The frequency dividing number of another frequency divider in the another communication block is set to a non-integer, and communication local signals supplied from the frequency divider to the mixers become non-quadrature signals having a phase difference at a predetermined offset angle from 90 degrees. The transceiver further includes a converting unit for giving a compensation offset amount having almost the same absolute value and having a polarity opposite to that of the offset angle to communication analog signals related to the mixer of the another communication block.

    • An electronic component for high frequency power amplification realizes an improvement in switching spectrum characteristics. The gain of an amplifying NMOS transistor is controlled by a bias voltage on which a bias control voltage is reflected. Further, a threshold voltage compensator compensates for a variation in threshold voltage with variations in the manufacture of the amplifying NMOS transistor. The threshold voltage compensator includes an NMOS transistor formed in the same process specification as the amplifying NMOS transistor and converts a variation in current flowing through the NMOS transistor depending on the variation in the threshold voltage of the amplifying NMOS transistor to its corresponding voltage by a resistor to compensate for the bias voltage. It is thus possible to reduce variations in so-called precharge level brought to fixed output power in a region (0 dBm or less, for example) low in output power.
    • 用于高频功率放大的电子部件实现了开关频谱特性的改进。 放大NMOS晶体管的增益由反射偏置控制电压的偏置电压控制。 此外,阈值电压补偿器通过放大NMOS晶体管的制造变化来补偿阈值电压的变化。 阈值电压补偿器包括以与放大NMOS晶体管相同的处理规范形成的NMOS晶体管,并且根据放大NMOS晶体管的阈值电压的变化转换为通过NMOS晶体管的电流的变化,由电阻器 以补偿偏置电压。 因此,可以减少在输出功率低的区域(例如,0dBm以下)带来固定输出功率的所谓预充电电平的变动。
