A relay receiver performs a heterodyne relay operation by using a receiving frequency converting portion, an intermediate frequency amplifying portion and an automatic gain controller. The variable band limiting portion limits an amplified signal output from the intermediate frequency amplifying portion to a band corresponding to the state of a band control signal, thereby transmitting an amplified signal. The band control portion is responsive to an automatic gain control signal outputted from the automatic gain controller, and outputs to the variable band limiting portion a band control signal for enabling the variable band limiting portion to limit the amplified signal to a narrow band in accordance with a decrease in the arriving level of the high frequency band received signal. Therefore, the frequency band of a communication signal amplified by the intermediate frequency amplifying portion is narrowed only when the arriving level of a received signal is low.
