Q3: Assume a transmitting antenna placed at AUK with a gain of 54 dB. The Pout of the transmitting antenna is 99 W. The signal is received by a satellite,

that is 37.5X10°m away from earth, with a gain of 26 dB. The signal is then routed to a transponder (a wireless receiver/transmitter devise) which has the following characteristics: a noise temperature of 50 K, a bandwidth of 36 MHz, a gain of 110 dB. Answer the following questions: a) Calculate the maximum path loss at 6.1 GHz b) Calculate the power at the output port of the satellite antenna in dBW. c) Calculate the noise power at the transponder input in dBW d) Calculate the carrier power at the transponder output (in dBW and Watt)
