摘要： PURPOSE: A gain adjusting device for a wireless repeater is provided to uniformly maintain and adjust an output strength of a frequency signal irrespective of the strength of the inputted frequency signal. CONSTITUTION: A signal distributor(51) distributes an inputted frequency signal. The first delay device(52) delays the frequency signal outputted from the signal distributor(51) during a certain time. The first BPF(Band Pass Filter)(53) separates a certain frequency band signal from the frequency signal outputted from the signal distributor(51). An attenuator(54) attenuates the frequency band signal outputted from the first BPF(53) at a certain level. The second delay device(55) delays the frequency band signal outputted from the attenuator(54) during a certain time. A signal synthesizer(56) synthesizes the output signals of the first and second delay devices(52,55).
