该文提出了5G通信载波聚合用B34&B39双接收滤波器的研制方法。首先根据产品指标,从双信道滤波器拓扑结构设计与信号端隔离两方面确定设计方案;再通过耦合模式模型结合全波仿真对产品进行仿真优化;最后通过有限元法/边界元法(FEM/BEM)进行器件性能验证。结果表明,产品实验与仿真结果图形吻合良好,且完全满足市场要求,证明了该文研究方法的可行性。

Research of B34 & B39 Diplexer for Carrier Aggregation of5G Communication

A development method of B34 & B39 SAW dual filter for 5G communication carrier aggregation is present in this article. First, according to the product index, the design is determined by the topology design and the isolate of the signal of the dual channel filters; then the product is simulated and optimized through the coupling-of-mode model combined with the electromagnetic full-wave simulation, and finally the FEM/BEM is used to verify the performance of device. According to the comparison between the production and the simulation results, the graphs are in good agreement and fully meet the requirements of market, which proves the feasibility of the research method in this paper.
