Abstract：
The invention discloses a radio frequency front end circuit of a software radio transceiver, which belongs to the technical field of wireless communication and has the following connection relation that a band-gap reference source circuit is respectively connected with a reconfigurable receiver radio frequency front end circuit and a reconfigurable transmitter radio frequency front end circuit; and a four-line serial synchronous interface circuit is respectively connected with the reconfigurable receiver radio frequency front end circuit, the reconfigurable transmitter radio frequency front end circuit and the band-gap reference source circuit. The radio frequency front end circuit of the software radio transceiver has the beneficial effects that: 1, the radio frequency front end circuit of the software radio transceiver supports a time division duplex (TDD) working mode and a frequency division duplex (FDD) working mode and has flexible configurability, the performance of the radio frequency front end circuit of the transceiver can be configured by the four-line serial synchronous interface circuit, and the requirements of different communication standards are met; 2, the performance indexes can be flexibly configured and the average power consumption of the completed transceiver is effectively reduced; and 3, a great amount of calibration circuits are integrated, so that thetransceiver meets the requirements of the communication standard.
