とを特徴とするＦＭ受信機。The high frequency signal from the antenna and the local oscillation output of the local oscillator 2 are mixed by the frequency converter 1 and converted into an intermediate frequency signal, and after the intermediate frequency signal is amplified by the first wideband intermediate frequency amplifier 5, FM detection is performed. The FM detection output is negatively fed back to the local oscillator 2, and the intermediate frequency signal is amplified by the second narrow band intermediate frequency amplifier 6J. 7. An FM receiver characterized in that a high-sensitivity FM detection output is obtained by detecting a signal using a FM receiver.
