Problems solved by technology

Because there are many differences in the working type, working frequency, working voltage, working current, working mode and working index of different types of power amplifier modules, and the number of power amplifier modules required by transmitters of different power levels is also different. Therefore, the debugging methods of these power amplifier modules are not the same, which leads to some problems: because there is no general method for deb

Abstract

The invention relates to a debug method of power amplification modules. The debug method mainly includes checking before power-on, to be specific, subjecting the power amplification modules to viewing and checking, measuring, classifying and managing; static debugging, to be specific, by adding current and voltage required by the technical indicator onto the power amplification modules, initially detecting accuracy of the power amplification modules; dynamic debugging, to be specific, by inputting dynamic signals to the power amplification modules, observing data of the power amplification modules with power amplified; managing and assembling after power-off, to be specific, managing the recorded data and, on the basis of the data managed, assembling the power amplification modules according to the technical requirements. The debug method can quickly, accurately and formally debug various power amplification modules.

Description

technical field [0001] The invention relates to a debugging method of a power amplifier module, in particular to a general debugging method of a power amplifier module suitable for fast and accurate debugging of various power amplifier modules in the field of radio technology. Background technique [0002] The terrestrial signal transmission system is an important part of radio and television technology, and its important component is the all-solid-state TV transmitter. With the development and update of the all-solid-state TV transmitter, both analog and digital transmitters adopt modular design.
