Abstract
A compensation method for radio frequency module performance, it is adding a module monitoring circuit and a radio frequency power detection circuit to an existing radio frequency module, meanwhile replacing an existing hardware compensation circuit with a radio frequency digital controlled attenuator. The method replaces hardware method by a method of combining software of the module monitoring circuit and hardware such as module monitoring circuit, radio frequency digital controlled attenuator and radio frequency power detection circuit, as well as intelligently compensates the radio frequency module by using data obtained by predefined table or formula/algorithm, so as to adjust each characteristic index of the device accurately and easily, thus to improve performance of the radio frequency module and further meet the requirement of working stability of the radio frequency module. The present invention further provides a radio frequency module improved by such method. As such radio frequency module can be automatically debugged and tested by tools such as computer, so production efficiency will be improved.
