摘要： A mobile station communicates with an access point (AP). The mobile station includes a low noise amplifier (LNA) path, a power amplifier (PA) path, a switch to select the LNA path or the PA path, and a controller directing the switch. The controller estimates amplifying power of the LNA, transmitting power and a sensitivity threshold of the PA. The controller receives a current received signal strength indication (RSSI) value of the AP. The controller determines whether amplifying power of the LNA path exceeds the PA sensitivity threshold. The controller transmits a selection signal directing the switch to select the LNA path if the amplifying power of the LNA path exceeds the sensitivity threshold of the PA.

摘要： A radio frequency (RF)-based communication terminal includes a first switching chip, a second switching chip, a comparison module, a low noise amplifier (LNA), a first filter, a power amplifier (PA), a second filter, and a control module. The comparison module compares the power of a radio signal Rx received from a base station with a pre-stored signal and to output a control signal according to the comparison result. The control module controls conductive modes of the first and the second switching chips according to the control signal. In the first conductive mode, a radio signal Tx is sent out from the PA and the second filter. In the second conductive mode, the radio signal Tx is exchanged to send out from the LNA and first filter.
