Signals for communication systems. In order to be able to deal with these modulated signals with a certain bandwidth, researchers must design a power amplification system with a certain bandwidth. The out-of-phase power amplification system has many advantages of high linearity, high efficiency and high output power. The traditional out-of-phase power amplification system The system amplifies the constant envelope signal, and its advantages are high output power and efficiency, and high linearity for the output modulated signal. However, the Chireix power combiner used in the traditional out-of-phase power amplification system is designed based on a single frequency point, so the bandwidth of this combiner is relatively narrow, which has a great impact on the combination of WCDMA signals, LTE signals and communication signals with a certain bandwidth , thus affecting the linearity, output power and efficiency in the entire passband, so the broadband out-of-phase power combiner has become one of the research hotspots in academia and industry. How to improve the bandwidth of the out-of-phase power combiner has become one of the hot spots in academia and industry.

However, the applicant found in the research that in fact the traditional Chireix power synthesizer is designed according to a single frequency point, so the bandwidth of this synthesizer is relatively narrow, which has a greater impact on the amplification of communication signals with a certain bandwidth, otherwise it will affect the The linearity, output power and efficiency of the entire out-of-phase power amplification system have a great influence, so the traditional out-of-phase power combiner can no longer meet the requirements of today's communication systems. Therefore, it is urgent to develop a broadband out-phase power combiner Increase the bandwidth to meet the linearity, output power and efficiency of the system in the passband to meet the requirements of high transmission data rates in current and future wireless communication systems. How to improve the bandwidth of the out-of-phase power combiner has become a research hotspot in academia and industry. Therefore, a broadband out-of-phase power combiner is designed.
