Unformatted text preview: (c) Compute the loss in dB/m. (d) Compute L and R, and show that the transmission line is low loss. 2 continued 3. Standing waves. A lossless transmission line with a characteristic resistance of 30 R = Ω is terminated by a load with impedance 30 L Z jX = + Ω . If the reflection coefficient is 0.64 0.48 j Γ = + , a) Find S b) Find m d in wavelengths c) Find X . 3 continued 4. Input impedance. A lossless transmission line of length ℓ and characteristic resistance 50 Ω is operated at 37.5 MHz and has a phase velocity 8 1.5 10 m/s × . a) Find the wavelength on the transmission line. b) When the line is terminated with a short circuit, the input impedance is 50 j Ω . Calculate the length of the transmission line. 4 continued...
