RADIO AMPLIFICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a radio amplification device capable of confirming the state of a failure of an active system without disconnecting a line during an operation in a standby system, easily performing maintenance and improving convenience.

SOLUTION: The radio amplification device includes: an input side RF switch 22 for inputting input signals to the active system or the standby system and inputting signals distributed when switching to the standby system to the active system; a directional coupler 30 for distributing the signals inputted to the standby system; a terminator 33 for terminating the inputted signals; and an output side RF switch 24 for connecting the active system or the standby system to an antenna 15 and connecting the output of an amplifier 13 to the terminator 33 when switching to the standby system. When switching to the standby system, one input signal distributed in the directional coupler 30 is transmitted from the antenna 15 through the output side RF switch 24, and the other signal is inputted to the amplifier 13 through the input side RF switch 22 and terminated in the terminator 33 through the output side RF switch 24.
