1. The problem statement, all variables and given/known data A lossless transmission line has an inductance of 9.0 nH / m and a capacitance of 3.6 pF / m. a) What is the line's characteristic impedance? b) Calculate the phase constant of a frequency of 1 GHz. 2. Relevant equations Equation of characteristic impedance of a transmission line: Z0 = sqrt( R+j2piL / G+2jpiC ) Where R and G = 0, because lossless transmission line. 3. The attempt at a solution For a I just used the equation above, but for task 2 I'm not sure what to do. I dont now how to get Sin/Cos to the equation so I can fint the phase constant. Do I need to do something to the equation above?
