In a satellite communication, the power delivered to a matched receiver, PR, is given by the Friis equation: where Pr is the received power, Pr is the transmiter power, G, is the transmitter gain and Gg is the receiver gain, r is the distance between the transmitter and receiver antennas and A is the wavelength. If the nominal transmitter output power is 100 Watts for a DIRECTV DBS and the transmitting antenna gain is 31dB, evaluate the received signal power if the 40cm diameter receiving dish has a nominal gain of 30DB. Assume that the operating frequency is 13GHZ, the range between the transmitting and receiving antennas is 35,786 km, and the receiving antenna is directly below the satellite.
