Exercise 8

The transmitter in the previous problem works with a receiving installation having an antenna gain of 32 dBi, a feedline loss of 1.5 dB, and a receiver noise figure of 2.5 dB. The bandwidth is 20 MHz at a carrier frequency of 6 GHz.
(a) What is the power at the receiver input, in dBm
(b) Calculate the antenna noise temperature, referred to the receiver input, assuming a sky temperature of 130 K.
(c) Calculate the receiver noise temperature.
(d) Calculate the system noise temperature, referred to the receiver input.
(e) Calculate the noise power, referred to the receiver input.
(f) What is the carrier-to-noise ratio at the receiver, in decibels
