  3. For the application of direct broadcast satellite ( dbs ), a ku - band high image rejection broadband mixer is designed using ads. it appears predominant performances when compared with common single balanced mixer

    針對衛星電視直播接收系統,用ads設計了一個寬頻帶、高鏡像抑制度、低噪聲的ku波段鏡像抑制混頻器,並同普通平衡混頻器進行了對比分析,顯示了其優越的性能。
  4. This ku - band three channel receiver consists of spst modules, lna modules and image rejection mixer modules. these modules were designed and tested separately, then were assembled to the whole receiver. all the circuits were designed with small - sized devices so as to reduce the total size of the receiver. and the noise figure was considerably reduced because of the image rejection mixer

    另外,由於採用了鏡像抑制混頻器,從而使整機噪聲系數大為降低。在設計方法上,本文採用了先進的微波電路設計軟體ansoftserenade對所有的電路和系統進行設計、優化和模擬,大大的縮短設計周期,提高設計效率。
  5. Five cell circuits are designed, fabricated and tested, including 5. 625 degree and 45 degree using loaded - line phase shifter, 90 degree using 3db branch - line coupler phase shifter, 90 degree and 180 degree using switched - line with loaded - line phase shifter. according to the testing result of cell circuits, and requirement of ku - band six - bit digital phase shifter, the scheme for ku - band six - bit digital phase shifter is chosen

    本文對5 . 625度和45度相移位採用主線加載的加載線形式,對90度相移位採用3db支線耦合器形式和加載式的開關線形式,對180度相移位採用加載式的開關線形式,分別進行了五個單元電路的設計、製作與測試。
