    • PROBLEM TO BE SOLVED: To provide a receiver in a time division radio communication system, capable of protecting a receiving circuit against damage due to an excessive power amplitude signal with a relatively simple structure.SOLUTION: A receiver includes a distribution part which divides electric power, in response to input of a reception signal from an antenna, into a first signal and a second signal and outputs them, a resonance part which has different resonant frequencies depending on whether the radio communication system is in transmission or in reception, and a combining part which combines two different received signals into one signal and outputs it. The first signal and the second signal output from the distribution part are passed through different resonance parts respectively, and then combined at the combining part.
