高功率低损耗六路功分器的设计与分析
|
摘要
针对高功率微波对功率放大器轻重量和小体积的要求,采用基于功率分配合成技术中的同相叠加原理,设计了一种C波段的结构紧凑型窄带6路功率分配器。该分配器通过射频同轴N型连接器输入射频信号,通过环形无氧铜窄带线等相均分为6路。利用CST软件对该器件进行了初步结构优化设计和S-parameter模拟仿真,理论传输系数为-7.78 dB。结果表明,该器件能承受5.0~5.3 GHz的工作频率,功率容量达到1 000 W,各端口的功率传输效率达到97.5%以上,插入损耗为0.2 dB以内,完全可以满足使用要求。
In the light of the high-power microwave′s requirements of light weight and small size for power amplifier,the inphase superposition principle based on power allocation and synthesis technology is used to design a compact structure narrowband 6-channel power divider working in C-band. The RF signals are input into the divider through RF coaxial N-type connector,and divided into 6 in-phase channels equally through annular oxygen-free copper narrowband line. The CST software is adopted to carry out the preliminary structure optimization design and S-parameter simulation of the device,whose theoretical transmission coefficient is-7.78 dB. Simulation results show that the device can bear the working frequency of 5.0~5.3 GHz,its power capacity can reach up to 1 000 W,its power transmission efficiency of each port is higher than 97.5%,and its insertion loss is within 0.2 dB,which can meet the operating requirements completely.
