Q5) A satellite in geostationary orbit at (36000 km) has a (4 GHz) downlink transmitter which feeds (5W) into an antenna with (30 dB) gain. The ground station receiving antenna is parabola with diameter of (10 m), if the system operating over (20 MHz) signal band. Find (i) the noise figure of the ground receiving system necessary for maintaining (30 dB) input signal to noise ratio, (i) The link attenuation. (k =1.38 x10, T, = 290K).
