Abstract
PURPOSE:To improve a cross modulation characteristic, by providing a tuning circuit having the same characteristic as a tuning circuit of a radio receiver, on the output stage of an FET consituting an antenna booster amplifier, and constituting the tuning circuit so that the tuning frequency is controlled by the same tuning voltage. CONSTITUTION:An aperiodic type antenna booster amplifying circuit is converted to a tuning type antenna booster amplifying circui whose cross modulation characteristic is excellent. That is to say, a tuning circuit having almost same characteristic as a tuning circuit in a radio receiver is provided on the output stage of an FET 13. Namely, both a radio side tuning circuit and an antenna side tuning circuit are provided. As a result, immediately after receiving by the antenna, only a desired frequency is discriminated, and a cross modulation characteristic is improved.
