Abstract
A radio repeater receives signals having reception frequencies, converts the received signals into signals having carrier frequencies, and transmits the converted signals. The radio repeater is applicable to communication in a cordless telephone system, a land-mobile radiotelephone system, or the like. With a conventional radio repeater, receivers and transmitters have to be installed for respective frequencies, respectively. With this radio repeater, an intermediate-frequency converter and a transmission power amplifier are used for both transmission and reception of signals in common, thereby reducing the number of component parts, and making the repeater compact.
