01: A satellite broadcast system operates at 12.45 GHz, with a transmit power of 120 W, and a transmit antenna gain of 34 dB. The distance from the geostationary satellite to Earth is 39,000 km. The 0.457 m receiving dish antenna has a gain of 33.5 dB and the required minimum P, is -100 dBm. Find the link budget for the received power at the antenna terminals and the link margin of the system.
