<p>PURPOSE: A combining device and a control method for transceiving a signal division are provided to maximize an effect blocking a signal which is leaked from a transmitting unit to a receiving unit by adaptively changing an attenuating value of an attenuator. CONSTITUTION: An attenuator(630) is an variable attenuator which can control a attenuating level variably. A signal strength measuring unit measures signal strength of a transmitting leaking signal in a low noise amplifier device. A receiving unit(130) is a low noise amplifier which amplifies an output signal by subtracting the output signal of attenuator from an output signal of a port.</p> |
