Abstract

The invention discloses an automatic debugging and testing system and a method for intermodulation of a power amplifier module. The system comprises an input mixer, an analog-to-digital converter (ADC), a digital attenuator, a digital-to-analog converter (DAC), an output signal mixing and amplifier, an FPGA chip, a communication module and a clock generation module, wherein inner program modules of the FPGA chip comprise an ADC interface module, an FFT module, a power detection module, a dual tone signal generation module, an intermodulation calculation module, an intermodulation value comparison and judgment module and a DAC interface. Automation of debugging and testing during the power amplifier module production process can be realized, the efficiency is improved, and the power amplifier module production cost is reduced.

Description

technical field [0001] The invention relates to the field of automatic debugging and testing of power amplifier modules, in particular to a system and method for automatic debugging and testing of power amplifier module intermodulation. Background technique [0002] With the development of society and economy, the manufacture of wireless communication equipment needs to be automated and intelligent. The power amplifier module is the signal amplification part of wireless communication equipment, and its third-order and fifth-order intermodulation directly affect the signal quality of the power amplifier. The main factor affecting the third-order and fifth-order intermodulation of the power amplifier module is the grid voltage level of the power amplifier tube. In the production and debugging of power amplifiers, signal sources and spectrum analyzers are mainly used manually, which is low in efficiency and high in cost. Contents of the invention [0003] Aiming at the probl...
