The present invention belongs to the technical field of data chain communication, especially relates to a radio frequency transmitter refined standing-wave protecting circuit and method suitable for radio frequency front-end module portions in a data chain end machine. An emitting output end of a power amplifier at the radio frequency front end is configured to perform power signal forward coupling and the radio frequency signals are subjected to positive detection to monitor the output of the radio frequency signals; one end of a bridge of a receiving end (the received radio frequency signalsare subjected to processing through a cavity filter, an isolator and the bridge and enter a power division limiter) of the radio frequency front end is connected with a detector to perform reflectionpower signal detection to detect the intensity of the reflection signals. Through comparison of voltages of positive and negative detectors, the reflection signal intensities of the antenna port in different standing-wave values are determined to adopt corresponding circuit protection measures. The radio frequency transmitter refined standing-wave protecting circuit and method cannot lose the positive power at the output end of the emitting chain, and when the standing wave is 5 or in a worse condition, the bearing power of the receiving end limiter is small and the limiter recovery time is increased so as to effectively improve the end machine performances.
