An antenna with a radiation resistance of 48 ohms, a loss resistance of 2 ohms, and a reactance of 50 ohms is connected to a generator with open-circuit voltage of 10 V and internal impedance of 50 ohms via a A/4-long transmission line with characteristic impedance of 100 ohms. (a) Draw the equivalent circuit (b) Determine the power supplied by the generator ſch Determine the nowaser radiated by the antenna

A system has a forward power of 60 W, reflected power of 3 W, and transmission line loss of –3 dB. What will be the observed loss on the ground? A system has a forward power of 200 W and a reflected power of 15 W, what is the return loss?

A 25-mV sinusoid at a frequency of 400 Hz is applied to an FM generator. If the deviation constant for the FM generator is 750 Hz/10 mV, determine 1. The frequency swing generated by the FM generator, in kHz = 2. The rate at which the carrier frequency is being deviated, in Hz

a.What is the attenuation of 350 ft of RG-11 U coaxial cable at 100 MHz?b. A transmitter has an output power of 3 W that is fed to an antenna through an RG58A/U cable 20 ft long. How much power reaches the antenna?c. Two engineers have a disagreement over the selection of transmission line for connections within a 100m Data Centre on a project that is at risk for cost overrun. The first engineer is arguing in favor of using multi-mode fibre while the second engineer would like to use single mode fibre. You are the project engineer. Decide which of the two transmission lines to use and justify your answer.d. For typical silica optical fibres with ncore = 1.45 and Δ = 5 x 10-3, calculate nclad and NAe. For a typical silica fibre with D (@ λ = 1.3μm) = 2.5 nm ps/km and a semiconductor laser source centred on λ = 1.3μm with Δλ = 4nm: the bandwidth length BL ≈ 100 Gbps km (singlemode, step-index). What transmission speed is possible at a distance of 5km?f. A link from point a to point b is…
