Description

technical field [0001] The invention relates to the field of instrumentation testing, in particular to a radio frequency power amplifier self-adaptive testing system and a testing method thereof. Background technique [0002] Radio frequency power amplifier (hereinafter referred to as power amplifier) ​​is a kind of electronic product which is widely used at present. However, when the ambient temperature changes greatly, the hardware circuit characteristics of the power amplifier will change accordingly, which will have a relatively large impact on the performance of the power amplifier. In order to overcome this effect and make the performance of the power amplifier as consistent as possible at different temperatures, a temperature compensation circuit must be added to the design of the power amplifier. When the temperature of the environment changes, the temperature sensor in the temperature compensation circuit detects the temperature change value of the environment at t...
