Problem 6: Page 752: Chapter4.2. When communicating with a geostationary satellite from Earth, the distance between TX and RX is approximately 35,000 km. Assume that Friis law for free-space loss is applicable(ignore any effect from the atmosphere) and that stations have the parabolic antennas with gains 60 dB (Earth) and 20 dB(satellite), respec- tively, at the 11-GHz carrier frequency used (a) Draw the link budget between transmitted power Prx and received power PRx (b) If the satellite RX requires a minimum received power of - 120 dBm, what transmit power is required at the Earth station antenna
