A dual type TDD(Time Division Duplex) transceiver is provided to obtain a sufficient isolation between an Rx path and a Tx path without a switch or a hybrid and to suppress an internal resonance state. A dual type TDD transceiver comprises the first device(350) and the second device(360), which independently receive Tx signals and Rx signals. The first device(350) and the second device(360) are connected to each other so that an Rx signal inputted to the first device(350) and an Rx signal inputted to the second device(360) respectively are outputted to a port of the second device(360) and a port of the first device(350). The first device(350) comprises the first isolation unit coupled to a port, to which a Tx signal is inputted, and the second isolation unit coupled to a port, to which an Rx signal is inputted. The second device(360) comprises the third isolation unit coupled to a port, to which an Rx signal is inputted, and the fourth isolation unit coupled to a port, to which a Tx signal is inputted. The first through fourth isolation units respectively comprise circulators(400-406).
