摘要： A communication terminal and a driving method thereof are provided. The driving method of a communication terminal includes: forming a transmitting path and an absorption path by controlling a time division duplex (TDD) switch in a transmitting mode to isolate the transmitting path and the receiving path from an absorption path, the transmitting path transmitting a transmitting signal in a wireless scheme, and the absorption path diverged from the transmitting path through a circulator of the TDD switch to block a reflecting signal in the transmitting signal reversely transferred to the transmitting path; processing the transmitting signal through the transmitting path. Because a TDD switch has an isolation function, insertion loss in a transmitting path may be suppressed.
