摘要

PROBLEM TO BE SOLVED: To provide an allotter which hardly receives an effect of external noise and hardly radiates an unnecessary radiation.;SOLUTION: In the allotter 1 for a ground wave TV broadcast, a power-supply voltage VCC of an amplifier 7 is imparted from the outside through an RF output terminal 4, and a control signal C for controlling switches 5 and 6 changing over whether or not a high-frequency signal is amplified by the amplifier 7 is imparted from the outside through the RF output terminal 3. Consequently, a power supply voltage input terminal 54 and a control signal input terminal 75 hardly receive effects of external noise as compared with a conventional input terminal projected to the outside of a box body 70, and the radiation of the unnecessary radiation is suppressed.;COPYRIGHT: (C)2009,JPO&INPIT
