Description
Summary:There is a certain relationship between the system noise figure and each channel noise figure of the multi-channel phased array receiver. In this paper, theoretical derivation is proposed to find the relationship between the system noise figure and each channel noise figure based on the theory of noise figure and Y-factor measurements. Then with ADS software simulation, simulation model is built and results verify the correctness of the formula. Finally, a 9 channels phased array receiver is used to test the system noise figure and the channel noise figure. Test results demonstrate that theoretical formula corresponds to the practical relationship between system noise figure and channel noise figure.
