Abstract

The invention provides a circulator power amplifier circuit and a design method thereof, wherein the circulator power amplifier circuit comprises a power amplifier, a circulator, a power load and a load, wherein the output end of the power amplifier is connected with the input end of the circulator, the load is connected with the output end of the circulator, the power load is connected with the load end of the circulator, the circulator is an N-level circulator or M-level circulator, and N and M are integers of more than 1. The circulator power amplifier circuit designed by adopting the circulator power amplifier circuit is improved in isolation degree of the circulator, and has great importance of improving the standing wave of the power amplifier, ensuring that indexes are stable, avoiding the mismatch and damage of the power amplifier and improving the reliability of the power amplifier.

Description

technical field [0001] The invention relates to the communication field, in particular to a circulator power amplifier circuit and a design method thereof. Background technique [0002] Facing the current increasingly fierce market competition, the performance of base station products is the main focus of competition in the industry. As an important part of the base station, the power amplifier unit is directly related to the quality of the transmitted signal and the communication effect. [0003] As the field of power amplifiers changes to high efficiency, high linearity, peak-to-average ratio, and high bandwidth, the reliability requirements for power amplifiers are more stringent. In the power amplifier design, the circulator is generally used between the output end of the power amplifier and the load (antenna, duplexer, etc.) to realize the one-way transmission of the signal. , to improve the standing wave of the power amplifier, increase the reverse isolation, and avoi...
