A compensation method for radio frequency module performance, said radio frequency module is provided with a radio frequency input power detection circuit, a radio frequency output power detection circuit, a module monitoring circuit, a power amplification circuit and a radio frequency digital controlled attenuator. The soft program running in the processor of the module monitoring circuit adjusts parameters of the radio frequency module according to querying predefined compensation table or according to the compensation data calculated based on predefined formula/algorithm, thus reducing influence of ambient temperature to linearity, gain, radio frequency power detection accuracy of the radio frequency module, as well as avoiding gain decrease of the radio frequency module. Moreover, a radio frequency module improved by such method is also provided. As said structure of above mentioned method is employed by the radio frequency module, monitoring method according to this structure is able to automatically debugging and testing by using tools such as computer, thus improving the production efficiency.
