For the satellite communication system shown below, the transmitter and receiver stations are at the same distance from the satellite, i.e., 36,000 km.
a) The uplink path loss Lu is dB. Don't include antenna gains.
b) The downlink path loss La is dB. Don't include antenna gains.
c) If Pin = -35 dBW, the power received at the satellite is dBW. Consider gains marked in the figure.
d) If the power output of the satellite amplifier gamp is 18 dBW, the power output at the receiver Pout is dBW. Consider gains marked in the figure.
