Question

A receiver with operating frequency fop=12GHz has antenna noise temperature Tin=23 K, LNA gain Grf=31 dB and LNA noise temperature Trf=47 K, mixer gain Gm=2 dB and mixer noise temperature Tm=700 K, IF gain Gif=24 dB and IF noise temperature Tif=800 K. Calculate the receiver system noise temperature. Calculate the carrier to noise ratio ((C)/(N)) in dB for a geostationary satellite at 90 degrees elevation if the noise bandwidth is Bn=25MHz, EIRP is 42 dbW and the gain of the receiving antenna is Gr=58 dB (neglect other losses). If the aperture efficiency is etar=63%, calculate the diameter of the receiving antenna Dr in meters. What should be the new diameter Drnew in meters of the receiving antenna to increase( C)/(N) by 1 dB? (c=300000 k(m)/(s) , h=35786 km , k=1.39*10^(-23))
