EEE 445 Homework #2 Solutions 2.2 A transmission line has the following per unit length parameters: L = 0.2 H/m, C = 300 pF/m, R = 5 /m, and G = 0.01 S/m. Calculate the propagation constant and characteristic impedance of this line at 500 MHz. Recalculate these quantities in the absence of loss ( R = G = 0). Solution:  1 m 33 . 24 2259 . 0 j C j G L j R 03 . 0 82 . 25 0 j C j G L j R Z In the absence of loss: 82 . 25 Z m 33 . 24 0 -1 j 2.6 RG-402U semi-rigid coaxial cable has an inner conductor diameter of 0.91 mm, and a dielectric diameter (equal to the inner diameter of the outer conductor) of 3.02 mm. Both conductors are copper, and the dielectric material is Teflon. Compute the R , L , G , and C parameters of this line at 1 GHz, and use these results to find the characteristic impedance and attenuation of the line at 1 GHz. Compare your results to the manufacturer’s specifications of 50 and 0.43 dB/m, and discuss reasons for the difference.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
