基于ads的帶阻濾波器設(shè)計-預(yù)覽頁
【正文】 標如下：中心頻率：6GHz；相對帶寬：9%；帶內(nèi)波紋： 。（1） 設(shè)置微帶線參數(shù)。（5） 在【LineCalc】計算窗口，繼續(xù)計算將頻率Freq 設(shè)置為 6 GHz將微帶線的特性阻抗設(shè)置為 50 Ohm點擊【Synthesize】按鈕可計算出微帶線的寬度 W = （6） 在原理圖畫圖區(qū)中，計算終端開路的微帶線MLOC.（7） 在【LineCalc】計算窗口，設(shè)置：將頻率Freq 設(shè)置為 6 GHz將微帶線的特性阻抗設(shè)置為 Ohm將微帶線的長度相移設(shè)置為 90度點擊【Synthesize】按鈕可計算出 微帶線的寬度 W = 和微帶線的長度 L = 。（2）在原理圖的元件面板列表上，選擇微帶線【TlinesMicrostrip】元件面板上出現(xiàn)與微帶線對應(yīng)的元件圖標。再對原理圖中TL2和TL3進行設(shè)置如下：TL2 的導(dǎo)體寬度設(shè)置為 W = x1 mmTL3的導(dǎo)體寬度設(shè)置為 W = x1 mm （3）設(shè)置T形結(jié)Tee1，Tee2，Tee3如下（單位mm）：Tee1 設(shè)置為 W1= W2=x1 W3=x2Tee2 設(shè)置為 W1=x1 W2=x1 W3=x3Tee3 設(shè)置為 W1=x1 W2= W3=x2 （4）設(shè)置終端開路的微帶線MLOC 如下：微帶線TL5的寬度設(shè)置為 W = x2 mm微帶線TL6的寬度設(shè)置為 W = x3 mm微帶線TL7的寬度設(shè)置為 W = x2 mm （5）在原理圖的工具欄，選擇變量【var】按鈕，插入原理圖中，雙擊VAR，打開【Variables and Equations】對話框，在對話框中分別對x1，x2，x3進行設(shè)置 其結(jié)果如下：（6）在原理圖的元件面板列表上，選擇優(yōu)化元件【Optim/Stat./yield/DOE】項，在優(yōu)化的元件面板上，選擇優(yōu)化控件Optim插入原理圖的畫圖區(qū)，并選擇目標控件Goal插入原理圖的畫圖區(qū)，共4個。 4 心得體會 這次課程設(shè)計總的來說不是特別容易，在課堂上雖然學了不少的理論知識，可當真正實踐的時候就發(fā)現(xiàn)自己懂的太少了，這次的仿真軟件完全是自學的，自己圖書館查資料，上網(wǎng)找資料，在查找和閱讀中確實學到挺多知識，也對ADS的仿真過程以及帶阻濾波器的原理有了更深刻的理解，在設(shè)計過程中遇到不少的問題，但都在我們組員的共同努力下找到解決辦法，大家共同努力，共同進步，通過這次課程設(shè)計更加體會到實踐對于理論的重要性，平時基本都是上課，實踐的機會很少，以后應(yīng)該加強這方面的練習。 your employer dismisses you and you think that you have been dismissed unfairly.For more information about dismissal and unfair dismissal, seeagainst the disciplinary action your employer has taken against you.
