摘要
介绍的X波段收发共用双圆极化馈源是为了拓展海外市场新研制开发的产品。工作频段:接收频段7.25~7.75GHz,发射频段7.90~8.40GHz。该频段目前在我国尚未应用,但随着我国军事事业的发展,该频段在我国的应用为时不远。本文介绍该馈源的工作原理,设计方法及实测结果。该馈源具有低电压驻波比、低插入损耗、高收发隔离度(在同极化和正交极化条件下)等特点,电器性能达到国外同类产品水平。
The product of X- band couple circular polarization feed is researched in order to exploit the oversea market. Frequency range:receive 7.25 -7.75 GHz, transmit 7. 90-8. 40 GHz, The band has not been applied in China at present, but with the development of our country military affairs, it is not too far for the band to be applied. Introducing design principle and method as well as measurement results. The advantages of the feed :low VSWR,low insertion loss and high isolation(at co - pol and cross - pol), The electricity performances of the feed reach to same level as same product abroad.
