- Since S = 1.7 in a transmission line to be used at 2 GHz; What is the length, in cm, of the parallel lateral line required to match the transmission line to the load impedance?arrow_forwardGiven the Personal Communications Service (PCS) extension to the Hata Model with a measured distance, d = 30 km, transmitter height, hte = 100 m, receiver height, hre = 7 m, and BS transmitter radiates an EIRP of 5 kW at a GSM carrier frequency of 925 MHz, evaluate: (a) The median path loss, L50 in dB (assume used in a medium sized city). (b) The median path loss, L50 in dB (assume used in a metropolitan center). (c) The power at the receiver, Pr in dB (assume a unity gain receiving antenna). (d) The received path loss, PL in dB.arrow_forward"A transmission line with negligible attenuation has L = 0.1 uH/ft and C = 0.2 nF/ft and is typically operated at 100 MHz. What is the velocity of propagation (in 10^8 m/s) of the signal along this line? Enter only the numerical value. No need for the unit. Use four decimal places (if the answer is not an integer). For example, the calculated value is 3x10^8 m/s, then enter 3."arrow_forward

- Estimate the corona loss for a 3-phase, 110 kV, 50 Hz, 150-km-long transmission line consisting of three conductors, each of 10 mm diameter and spaced 2.5 m apart in an equilateral triangle formation. The temperature of the air is 30oC and the atmospheric pressure is 750 mm of mercury. Take the irregularity factor as 0.85. Ionisation of the air may be assumed to take place at a max voltage gradient of 30 kV/cm.arrow_forwardA 132 kV, three-phase, 50Hz transmission line uses 18 mm diameter, equally spaced conductors. Determine the spacing between these conductors, if it is to be designed such that the corona inception voltage is 5% higher than the normal operating voltage of the line at 40oC.

- Use the free space model and the following equation to compute the received power in dBm for a 900 MHz signal travelling to a receiver 200 meters away. Assume the transmitter antenna gain is 10 dB and the receiver antenna gain is 3 dB. Assume the power at the transmitter is 22 dBm. (Note: Pr dBm is the received power in dBm, Pt dBm is the transmitted power in dBm, PL dB is the free space path loss in dB, Gt dB and Gr dB are the antennas gains at the transmitter and receiver, expressed in dB, respectively) state the answer in the correct units and show all your computations to receive creditarrow_forwardA Three-Phase, 180 KV, 75 Hz Transmission Line consists of 1.2 cm radius conductors spaced at 2.4 meters apart in an equilateral triangular formation.
