Problems solved by technology

The application of digital predistortion (DPD) and Doherty technology can greatly improve the linearity and efficiency of the power amplifier, but it increases the complexity of the equipment, which in turn increases the difficulty of production and debugging
[0003] The Doherty-based power amplifier uses two or more power amplifier tubes, and each power amplifier tube has one or more grid voltages. The performance of the power amplifier module is affected by the multiple grid voltages of the above multiple power amplifier tubes. Increased the difficulty of debugging the power amplifier

Description

technical field [0001] The invention relates to the power amplification technology in the field of mobile communication, in particular to a device and method for quickly commissioning and testing the grid voltage of a power amplifier module (Doherty). Background technique [0002] With the advent of the third-generation broadband digital mobile communication (WCDMA / CDMA2000 / TD-SCDMA) era, various communication operators have higher and higher performance requirements for communication system base stations, RRUs, and repeaters. And as the most important module, the power amplifier module, puts forward higher requirements for its indicators, environmental protection and energy saving performance. The application of digital predistortion (DPD) and Doherty technology can greatly improve the linearity and efficiency of the power amplifier, but it increases the complexity of the equipment, which in turn increases the difficulty of production and debugging. [0003] The Doherty-ba...
