Radio base station

Abstract

There is provided a radio base station which can automatically correct variation in gain of a mast head amplifier and variation in transmission loss due to the length, type and maintenance conditions of a feeder and can minimize an error of the gain of a received signal. The radio base station of the present invention has a terminating set and an antenna and includes a mast head amplifier selecting any one signal of a first signal inputted from the terminating set and a second signal inputted from the antenna to amplify and output it. The radio base station of the present invention also includes a base station receiver connected to the mast head amplifier adjusting an intensity of the first signal so that the intensity of the first signal is a predetermined value to set a first gain of the first signal when inputting the first signal from the mast head amplifier, and adjusting an intensity of the second signal based on the set first gain when inputting the second signal from the mast head amplifier.
