摘要： A disclosed bi-directional amplifier circuit allows the use of data over coaxial cable protocols (for example, MOCA) over existing and newly developed cable TV systems. Through the use of directional couplers on the AP side of the bi-directional amplifier, equal bi-directional power amplification can be achieved. According to a general aspect, an apparatus includes a bi-directional amplifier (1212) configured to amplify signals having a first direction and to amplify signals having a direction opposite the first direction. The apparatus also includes a bi-directional power detector (1202-1204) coupled to the bi-directional power amplifier so as (1) to detect power in a signal having the first direction before the signal having the first direction is amplified by the bi-directional power amplifier, and (2) to detect power in a signal having the opposite direction after the signal having the opposite direction is amplified by the bi-directional power amplifier.

摘要： A method and an apparatus for extending the receiving (Rx) dynamic range of RF (Radio Frequency) transceiver in TDD system is provided. The apparatus comprises: a RF switch having a receiving mode for receiving a signal and a transmitting mode for transmitting a signal; a low noise amplifier for amplifying the signal from the RF switch; a receiving link for transforming a signal from the low noise amplifier into a baseband signal; and a baseband processing part for processing signal from the receiving link, wherein when receiving a signal, the baseband processing part switches the RF switch between the receiving mode and the transmitting mode as a function of the power level of the signal compared to a threshold.
