    • A high frequency receiver capable of stably canceling interference by a transmission signal even if a transmission signal input from a TV antenna is changed. Phase shifter (212) for changing a phase of an interfering distributed transmission signal, detector (216) for detecting a level of a transmission signal included in a receive signal input via an antenna, and level regulator (213) for changing a level of the distributed transmission signal in accordance with this level are provided. A signal input via level regulator (213) and phase shifter (212) and a receive signal are synthesized to be input into mixer (206). Since a transmission signal can be cancelled even if a transmission signal input from an antenna is changed, a high frequency receiver can receive a signal stably when a transmission signal is changed.
    • 即使从TV天线输入的发送信号发生变化,能够稳定地消除发送信号的干扰的高频接收机。 用于改变干扰分布式发送信号的相位的移相器(212),用于检测包括在通过天线输入的接收信号中的发送信号的电平的检测器(216)和用于改变经由天线输入的电平的电平调节器(213) 提供了根据该级别的分布式传输信号。 通过电平调节器(213)和移相器(212)的输入信号和接收信号被合成输入到混频器(206)中。 由于即使从天线输入的发送信号发生变化也能够消除发送信号,所以当发送信号变化时,高频接收机能够稳定地接收信号。
