微带线计算工具 滤波器两边的引出线是特性阻抗为50欧姆的微带线，它的宽度W可由微带线计算工具得到，具体方法是点击菜单栏Tools-＞LineCalc-＞StartLinecalc，出现一个新的窗口(如下页图)。
在窗口的SubstrateParameters栏中填入与MSUB中相反的微带线参数。
在CpmpnetParameters填入中心频率(本例中为3.05GHz)。
Physical栏中的W和L分别表示微带线的宽和长。
Electrical栏中的Z0和E_Eff分别表示微带线的特性阻抗和相位延迟。
点击Synthesize和Analyze栏中的箭头，可以进行W、L与Z0、E_Eff间的相互换算。
填入50Ohm和90deg可以算出微带线的线宽1.52mm和长度13.63mm(四分之一波长)。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
