Noise temperature

The temperature (Ta) that yields the available power spectral density from a source. It is obtained when the corresponding reflection coefficients for the generator and load are complex conjugates. The relationship to the available power Pa is

where k is Boltzmann’s constant
and B is the bandwidth of the power measurement.

The power spectral density across the measurement band is to be constant.
