A signal transceiving device in a communication system and a method are provided to support both TDD(Time Division Duplexing) and FDD(Frequency Division Duplexing) modes, and to realize high isolation between transceiving paths in TDD and FDD systems using high power. A signal transceiving device comprises as follows. Transceivers transmit and receive signals corresponding to TDD and FDD modes. A duplexer(307) transceives signals through an antenna, and branches the signals into transmission signals and reception signals. A switch unit(305) controls paths of the transmission signals and the reception signals according to a signal transceiving method used in the signal transceiving device. |
