    Bias-Tee Design for an RF Circuit

    Am having a difficult time with Bias-Tees. I do not know how to get the characteristic impedance (although I assume it uses the equation below) How would you use this if you are not given the R and the G? You could guess L and C. I know how Bias-Tees work and that a typical schematic would...

    Help with Homework Equation: Input Impedance

    Homework Equation: I do not think I am getting the correct answer for this problem when I do it out by hand. Do I plug the necessary values into the equation shown above or do I say that because it is an infinite line that the characteristic impedance is equal to the input impedance? If the...

    Characteristic Impedance of a coaxial cable

    Image 1: Image 2: I am attempting to learn about transmission lines and am having problems with this homework problem. For part a, I have derived an equation for the maximum electric field within the dielectric. I came up with: with r being the radius and the electric field decreasing with...
