A channel repeater is provided to improve channel use efficiency of a communication apparatus and a repeater used in mobile communication and fixed communication. A first band unit(40a) relays a frequency signal supplied from a signal distributor(30). One or more channel units(50) set up each frequency channel. A signal combiner(60) combines the first band unit and a signal outputted through the channel unit in one signal. A first radio frequency power amplifier(70a) amplifies and outputs the combined signal. A second band pass filter(10b) outputs the signal amplified in the first radio frequency power amplifier to the outside, or performs band-filtering of the signal inputted from an external terminal or a base station.
