Problems solved by technology

The method of manual debugging is obviously affected by environmental and human factors. For example, the temperature difference between the temperature during debugging and the ambient temperature of the power amplifier field application will have some impact on the parameters that were debugged at that time, thus affecting the performance of the power amplifier. , and this method is only suitable for occasions with narrow bandwidth and low requirements; if the method of setting a fixed pilot frequency is used, the complicated debugging work will be saved, but this method is an open-loop control method, that is, when the actual When the working frequency band changes, the fixed pilot cannot have any adjustment effect on the working performance of the power amplifier.
