1. The problem statement, all variables and given/known data A satellite link has a transmitted power output of 0.5W. This power is increased in the direction of transmission by the transmitter antenna, which has a 20dB gain. The RF signal is attenuated by a path loss of 200 dB. The total noise level at the receiver input is estimated to be 2dBf. The desired SNR at the input receiver is 15dB. Determine the min. antenna gain G(dB) that will meet the specifications The front end of a television receiver, having a bandwidth of 7 MHz and operating at a temperature of 27°C, consists of an amplifier having a gain of 15 followed by a mixer whose gain is 20.The amplifier has a 300-Ω input resistor and a shot noise equivalent resistance of 500 Ω. For the converter, these values are 2.2 kΩ and 13.5 kΩ respectively, the converter load resistanceis 470 kΩ. Calculate Req for this television receiver 2. Relevant equations 3. The attempt at a solution I have no idea on how to do it. I was thinking of getting the antenna gain in the receiver then get the sum of receiver input and output to 0. Unfortunately, I do not know how to convert SNR to antenna gain. In the second problem, I totally got no idea. The answer was given to us, which is 50dB and 875ohms respectively. Please guide me to achieve the answer.
