PURPOSE: A wireless repeater using a solar battery is provided to stop an operation of a reverse amplifier and reduce output of a forward amplifier if a reverse signal does not exist, thereby reducing consumption power. CONSTITUTION: A forward output controller(31) amplifies a signal inputted from the first antenna. A forward amplifier(32) amplifies a forward direction output controller signal. A reverse preamplifier(41) amplifies a signal received from the second antenna. A reverse amplifier(42) amplifies reverse preamplifier output. A switch(44) cuts off power provided to the reverse amplifier. |
