The invention discloses a gain calibration method and device for radio frequency equipment. The method includes: obtaining a first reference calibration value according to the equipment model information and production batch information included in the acquired equipment information of the equipment to be calibrated, and then performing gain calibration on the equipment to be calibrated according to the first reference calibration value. Since the first reference calibration value is obtained from the calibrated equipment that is consistent with the equipment model information and production batch information of the equipment to be calibrated, the first calibration value has high reliability; and, compared with the current In the prior art, the gain calibration is performed by means of manual instrument measurement. The method adopted in the embodiment of the present invention is relatively simple to operate and relatively short in time, which effectively improves the efficiency of gain calibration of radio frequency equipment.
Description
technical field [0001] The present invention relates to the technical field of terminals, in particular to a gain calibration method and device for radio frequency equipment. Background technique [0002] At present, there are differences between the expected performance and actual performance of radio frequency equipment. There are many reasons for this difference, such as inconsistent manufacturing performance of components and performance changes of radio frequency equipment at different temperatures. In order to solve this problem, a variable gain circuit is usually added to the circuit, and the performance close to the expected performance can be achieved through dynamic adjustment in the later stage. [0003] The conventional adjustment method in the prior art is to manually measure the actual gain value of the radio frequency equipment through an instrument, then calculate the compensation value according to the obtained actual gain value and the expected gain value, ...
