摘要： The embodiments disclose a radio frequency loop test method and apparatus for testing frequency division duplexing transceiver in a radio communication system. The apparatus comprises a first directional coupling means and a mixer. The first directional coupling means is coupled with a duplex filter to receive, at a first port, a test signal from a transmitter via the duplex filter; the mixer is coupled with first directional coupling means on both sides to receive the test signal from a second port of the first directional coupling means, convert the frequency of the test signal from the transmitter to a frequency that is receivable by a receiver, and to output the converted test signal to the first directional coupling means, and the first directional coupling means is coupled to receive, at a third port, the converted test signal from the mixer and output, at the first port, the converted test signal to the receiver via the duplex filter.
