A C-band earth station has an antenna with a transmit gain of 54 dBi. The transmitter output power is set to 100 W at a frequency of 6.100 GHz. The signal is received by a satellite at a distance of 37,500 km by an antenna with a gain of 26 dB. The signal is then routed to a transponder with a noise temperature of 500 K, a bandwidth of 36 MHz, and a gain of 110 dB. i) Calculate the path loss at 6.1 GHz. Wavelength is 0.04918 m. ii) Calculate the power at the output port (sometimes called the output waveguide flange) of the satellite antenna, in dBW. iii) Calculate the C/N ratio, in dB, in the transponder. iv) Calculate the carrier power, in dBW and in watts, at the transponder output Hint: (a) = Lp199.6 dB; (b) Pr= -99.6dbW; (c) C/N = 26.4dB; (d) P+ = 11.0 W.
