10~45 GHz宽频段同轴输入窗设计
Design of 10-45 GHz wide-band coaxial input window
摘要
为满足微波管放大器对宽频段输入窗的需求，并保证馈源的真空密封需求，提出并设计了一种适用于宽频段微波放大器的同轴输入窗。该宽频段同轴输入窗采用渐变圆环形陶瓷，材料介电常数为9.3，窗片厚度为2.5 mm,内径为2.14 mm，外径为5 mm，渐变段长度为6.5 mm。利用三维高频电磁仿真软件CST对其建模分析，并对同轴内外结构尺寸和陶瓷渐变结构进行优化仿真，得出该宽频带同轴输入窗能够在10～45 GHz频带内实现插入损耗小于0.5 dB。
Abstract
In order to satisfy the demand of microwave amplifier tube for wide-band input window, a coaxial input window suitable for wide-band microwave device is designed. The material of the coaxial input window is tapered circular ceramic, whose permittivity is 9.3. The structure and size of coaxial and tapered ceramic are simulated by three-dimensional simulation software. Simulation results show that this coaxial input window can work in 10-45 GHz range with a less than 0.5 dB insertion loss.
