System and method for testing radio frequency power amplifier in mobile terminal

Abstract

The invention discloses a system and method for testing a radio frequency power amplifier in a mobile terminal. The system is composed of a signal module, a computer, a single-chip microcomputer, a radio frequency power amplifier, and a testing unit. The signal module is used for generating an original signal that is not processed; the computer is used for downloading a compiled testing code to the single-chip microcomputer by a serial interface; the single-chip microcomputer is used for controlling the radio frequency power amplifier to carry out amplification processing on the original signal according to the testing code; and the testing unit is used for testing whether the original signal after the amplification processing reaches the strength for antenna transmission. Therefore, the radio frequency power amplifier is tested by a relatively simple and high-speed way and the testing efficiency of the radio frequency power amplifier is improved.

AI Technical Summary

Benefits of technology

This patented technology allows for quick and easy testing of wireless communication devices' radios by downloading their own program codes onto an integrated circuit chip that controls how they work with signals transmitted over wires or optical fibers. By doing this, it simplifies the process of finding any issues affecting these components without having them be taken out manually during maintenance checks on older equipment.

Problems solved by technology

This patented technical solution for testing wireless communication devices involves performing various types of measurements during their production process or after they have been shipped from one location to another. However, this method requires modifications that can slow down the overall operation speed of the device being tested due to its complex hardware structure.
