Abstract

PURPOSE:To contrive to reduce the effect of a disturbing radio wave by providing an expansion circuit expanding a range of a tuning voltage corresponding to a desired local oscillation frequency and a tuning circuit connected and arranged in the vicinity of an RF amplifier and reducing a disturbing radio wave component in a received signal based on a tuning voltage. CONSTITUTION:A reception signal received from an antenna 1 is fed to a tuning circuit 22 via a buffer 21. On the other hand, an output tuning voltage VT of a PLL circuit 6 is fed to an expansion circuit 23, where the tuning voltage VTL whose range is expanded is formed and the result is fed to a tuning circuit 22. The tuning circuit 22, based on the incoming tuning voltage VTL, reduces the disturbing radio wave component in the reception signal and gives it to the RF amplifier 2. The reception signal of the desired frequency outputted from the RF amplifier 2 is fed to a mixer 4 via an LPF 3, where the signal is mixed with the frequency signal from the local oscillator 5 and the result is outputted from a terminal 24.
