摘要

According to the requirementof 3-mm wave radar, the ferrite switch scheme of the corresponding band is proposed. Through analysis on the principle and scheme,simulation and optimization design, processing technology, the ferrite high-speed switch was obtained featureing low insertion loss, fast switching time, low power consumption, high reliability. The ferrite switch has such good working performance in 3-mm band as VSMR of higher than 1.16, insertion lossα+≤0.58dB, isolationα―≥22dB 22dB and response timet≤2μs, which is of conference for the furthersimulation, design and process on the millimeter wave ferrite switch.%针对目前3mm波雷达要求，提出了相应频段的铁氧体开关方案。通过原理与方案分析、仿真优化设计和加工工艺的探索设计制作了一种具有插损低、开关转换时间快、功耗低和可靠性高等优点的3mm铁氧体高速开关。所研制的铁氧体开关在3mm频段内工作性能良好，性能为：输入电压驻波比VSWR≤1.16，正向损耗（插损）α+≤0.58dB，反向损耗（隔离度）α―≥22dB，开关响应时间 t≤2μs，为后续毫米波的仿真研究、加工技术手段提供了一定的方向与参考。
