    • A downconverter capable of being normally operated even in the case where a universal dual downconverter is made up by use of multiple downconverter circuits. The downconverter includes first and second downconverter circuits, and an amplification unit having at least a first amplifier LNA for receiving a horizontally polarized wave signal, and a second amplifier LNA for receiving a vertically polarized wave signal. If a Tone/Pola signal is a signal indicating a power-saving mode, a control circuit of the first downconverter circuit causes both a local oscillator and a frequency converter to be in a non-operating state, controlling a bias circuit such that power is supplied to the first amplifier LNA.
    • 即使在通过使用多个下变频器电路构成通用双下变频器的情况下,也能够正常工作的下变频器。 下变频器包括第一和第二下变频器电路,以及具有用于接收水平极化波信号的至少第一放大器LNA的放大单元和用于接收垂直极化波信号的第二放大器LNA。 如果音调/波拉信号是指示省电模式的信号,则第一下变频电路的控制电路使本地振荡器和变频器都处于非工作状态,控制偏置电路,使得功率为 提供给第一放大器LNA。
