1 A microwave antenna 25 K is coupled through a network 30 K to a microwave receiver with 60 K referred to its output Calculate the noise power at its input for a 2 MHz bandwidth

1. A microwave antenna ( = 25 K) is coupled through a network ( = 30 K) to a microwave receiver with  = 60 K referred to its output. Calculate the noise power at its input for a 2-MHz bandwidth. Determine the receiver's NF. (3.17 X 10-15 W, 0.817 dB)

2. A high-quality FM receiver is to be tested for SINAD. When its output contains just the noise and distortion components, 0.015 mW is measured. When the desired signal and noise and distortion components are measured together, the output is 15.7 mW. Calculate SINAD. (30.2 dB)
