Abstract
PURPOSE:To reduce cross modulation distortion and intermodulation distortion due to broad-band reception by covering the whole braod reception band with a group of preamplifiers receiving signals differing in band. CONSTITUTION:According to a signal which is applied to terminal 20 and corresponds to a channel to be received, change-over circuit 12 is changed over to supply the received signal to one of amplifiers 31-33 amplifying signals of respective divided bands of the whole reception band. Outputs of amplifiers 31-33 are applied to one terminal of 1st mixer 14 via change-over circuit 13 changed over corresponding to the signal from terminal 20. In this way, a group of preamplifiers 31-33 covers the whole band, so that a low-noise and low-distortion broad-band receiver circuit can be realized.
