With the progress of communication technology, RF wireless communication technology has made the rapid development. Wireless communication technology has become more and more mature and stable. Universal and miniaturization of RF transceiver system have become the important development directions. In this paper, the principle of RF transceiver based on Software Defined Radio technology is introduced, several common schemes are analyzed, and the advantages and disadvantages of the miniaturization and integration of each scheme are compared. Finally an integrated radio frequency (RF) Agile transceiver made by ADI is used to construct the hardware platform and realize a simple full duplex RF transceiver system.
