Radio communication apparatus

摘要

A radio communication apparatus comprises a transmitting circuit, a receiving circuit, an amplifier, a control circuit and a detecting circuit. The receiving circuit receives a signal from an opposite station such as a base station. The transmitting circuit transmits a signal to the opposite station. The amplifier amplifies the signal to be transmitted from the transmitting circuit. The control circuit controls the level of the transmission signal outputted from the amplifier. The detecting circuit detects the reception state in response to the reception level or the error rate of the signal transmitted from the opposite station. And the control circuit selectively switches, in response to the detection signal obtained from the detecting circuit, the output level of the transmission signal obtained via the amplifier from a high-level mode to a low-level mode when the reception state of the signal transmitted from the opposite station satisfies a preset value.
