Abstract: A mobile terminal switching antenna and a switching method thereof include an antenna, RF module, baseband chip, voltage dividing module, noise barrier module, DC blocking module, unidirectional conduction module, and antenna matching module. The baseband chip is coupled to the antenna via the RF module. The baseband chip is coupled to the antenna sequentially via the voltage dividing module, noise barrier module, and DC blocking module. The baseband chip is grounded sequentially via the voltage dividing module, noise barrier module, unidirectional conduction module, and antenna matching module. By the baseband chip not emitting or emitting the control signal to the antenna, the switching of the operative states of the antenna is thus realized, and the range of the frequency bands which can be received by the antenna is changed correspondingly, thereby greatly enhancing the receiving and transmitting performances and providing convenience to users.

Abstract: The present disclosure discloses a power-adjustable mobile phone and a power adjustment method thereof. The method comprises following steps of: a. determining whether a maximum power transmission instruction from a base station is received before establishing a phone call; b. determining whether an interrupt signal emitted from a range sensor is received after it is determined that the maximum power transmission instruction from the base station is received; c. setting a maximum output power of a radio frequency power amplifier (RFPA) to be a first output power when it is determined that the interrupt signal is not received, and setting the maximum output power of the RFPA to be a second output power when it is determined that the interrupt signal is received; and d. controlling the RFPA to output radio frequency (RF) signals with the maximum output power.
