5. Consider a point-to-point communication link operating at 38 GHz, using 35-dB dish antennas at each end. The radome loss is 2 dB at each end, and a 10-dB fade margin is required to allow for rain fades. If the transmit power is –10 dBm, the receiver noise figure is 7dB, the bandwidth is 50 MHz, and the link distance is 1.2 km, what is the signal-to-noise ratio at the receiver in dB? Assume that free-space loss applies.
