摘要： The present invention use the properties of a TDD-transmission on a specific mixer in such a manner that in the transmit mode a first RF signal is amplified in the mixer with an amplification factor greater than, or equal to, or less than one, and in the receive mode the received RF signal is mixed with a second RF signal.
