一种新型合路移相器

A New Type Combined Phase Shifter

文章对应用于工作频段为1885~2025 MHz、2515~2675 MHz移动通信基站天线的合路移相器进行了设计研究。给出了一种能够将合路移相器的合路功能和移相功能分开,并适合模块化设计的“品”字型三腔体结构合路移相器设计方法。同时为了进一步验证所设计合路移相器的性能指标,对使用该合路移相器的基站天线指标进行了详细设计说明,结果表明文章设计的合路移相器符合行业基站天线设计要求。

In this paper,the combined phase shifter is designed and studied for the base station antenna of mobile communication in the working frequency band of 1885~2025 MHz and 2515~2675 MHz.A design method of the shape of“Pin”word three cavity combined phase shifter is presented,which can separate the combining function and phase shifting function of combined phase shifter and is suitable for modular design.At the same time,in order to further verify the performance indicators of the designed combined phase shifter,the base station antenna indicators using the combined phase shifter are made detailed design description.The results show that the combined phase shifter designed in this paper meets the design requirements of the industry base station antenna.
