The signal received by the LNB is extremely weak and it has to be amplified before downconversion. The low-noise amplifier section of the LNB amplifies this weak signal while adding the minimum possible amount of noise to the signal. The low-noise quality of an LNB is expressed as the noise figure (or sometimes noise temperature). This is the ...
