A ka - band bpf would be developed and used in the rardar system 同時制做一只ka波段的波導濾波器,用于毫米波合成孔徑雷達系統(tǒng)中。
Based on those and the practical needs of some projects , the thesis mainly focuses on two different kind millimeter mixers : a ka band mixer and an ehf band mixer 根據(jù)以上分析和應用項目的實際需要,最后本文集中于對兩種混頻器的研制:一種ehf頻段混頻器;一種ka頻段混頻器。
So the low price , small bulk and high performance of front - end rf become more and more important . in this dissertation , a ka band multiplier chain is developed , which can be used for local oscillator 低價的、小型的、高性能的射頻收發(fā)前端的開發(fā)顯得越來越重要,本論文所研究的課題是ka波段倍頻鏈,要求把2ghz的信號倍增至36ghz 。
