When communicating with a geostationery satellite from earth,the distance between transmitter and receiver is approximately 35000km.assume that the friis law for free space loss is applicable and the stations have parabolic antennas with gains 60db and 20db at the 11ghz carrier frequency.
1) draw the link budget between transmitted power ptx and received power prx
2) if the satellite receiver requires a minimum received piwer of -120 dbm what transmit power is requires at te earth station antenna
