Patent ID: 8422959

Claim:
A compensation method for radio frequency module performance, wherein said radio frequency module is provided with a power amplification circuit ( 201 ), a radio frequency digital controlled attenuator ( 202 ), a radio frequency power detection circuit ( 203 ) and a module monitoring circuit ( 209 ), said method comprises: S 1 : Said module monitoring circuit ( 209 ) queries a predefined gain compensation table or calculates based on a predefined formula/algorithm according to the currently set frequency band and the collected temperature data to obtain a gain compensation data, which is sent to the radio frequency digital controlled attenuator ( 202 ), so as to adjust gain of the radio frequency module based on the said gain compensation data; S 2 : Said module monitoring circuit ( 209 ) queries a predefined linearity compensation table or calculates based on a predefined formula/algorithm according to the collected temperature data to obtain a linearity compensation data, which is sent to said power amplification circuit ( 201 ) after being converted into corresponding control voltage by digital-analog conversion, so as to control linearity of said radio frequency module; S 3 : Said module monitoring circuit ( 209 ) queries a predefined power compensation table or calculates based on a predefined formula/algorithm according to the collected temperature data to obtain a power compensation value, which is added to currently detected power detection value, so as to obtain a corrected power detection value.
