Abstract

The invention discloses a method for arranging a power amplifier auxiliary road grid voltage value. The method comprises: a Doherty power amplifier performance parameter is selected and hardware equipment is determined according to the performance parameter; and a peak value adjustment variable quantity is obtained in the hardware equipment according to the performance parameter index as well as the peak value is circularly adjusted according to the peak value adjustment variable quantity. According to the method and the apparatus for arranging the power amplifier auxiliary road grid voltage value, efficiency of mass production of Doherty power amplifiers can be improved and thus a problem of low production efficiency caused by discrete characteristics of the power amplifiers themselves can be solved; besides, cost of manual debugging can be saved. And meanwhile, indexes of the power amplifiers are in a balanced state.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for setting the grid voltage of a Doherty power amplifier. Background technique [0002] In the design of RF power amplifiers, efficiency and linearity are the two core indicators of power amplifiers. The existence of the two is a relationship that restricts each other. High-efficiency power amplifiers mean the deterioration of linearity indicators. Among the contradictions between the two, Doherty power amplifiers Emerged as the times require, with its unique design combined with the current mature DPD technology, it solves the bottleneck of the current power amplifier efficiency and linearity that are difficult to win. [0003] The power amplifier tube is a core device of the RF power amplifier, and its production process and process control are very complicated, which means that it is difficult for the batch power amplifier tubes provided by the power amplifier ...
