Abstract: A transceiver device and a power saving method thereof are provided. The transceiver device includes an attenuation estimation module, a transmitter, and a control module. The attenuation estimation module is coupled to a transmission path for estimating an attenuation value caused when a signal passes through the transmission path. The transmitter is coupled to the transmission path, for outputting a transmission signal. The control module is coupled to the attenuation estimation module and the transmitter. When the attenuation value is smaller than a default value, the output power of the transmitter is adjusted to be lower. Thereby, the power consumption of the transceiver device is decreased.

Abstract: A transceiver device and an impedance matching method are provided. In the impedance matching method, a plurality of matching modes is set. Each matching mode includes a default impedance and a corresponding default power. In addition, one of the matching modes is selected for outputting a transmission signal to a load. Besides, a response signal derived from the transmission signal is received. Further, whether the default impedance is matched with an impedance of the load or not is determined according to a parameter of the response signal. Thereby, the echo signal can be restrained from being generated.

Abstract: A transceiver device and a power saving method thereof are provided. The transceiver device includes a transmitter, a receiver, and a control module. The control module is coupled to the transmitter and the receiver. After the control module lowers the output power of either the transmitter, the receiver, or both of them, the control module checks a signal transmission between the transceiver device and a far-end device is normal or not. When the signal transmission between the transceiver device and the far-end device is abnormal, the control module readjusts the output power of the transmitter, the receiver, or both of them. Thereby, the power consumption of the transceiver device is decreased.
