Abstract
Firstly, the paper analyzes the principle of applying superconducting receiving technology to satellite payload. Combined with the advantages of superconducting receiving technology, it establishes the circuit model of single-antenna receiving system. Secondly, it sets the relevant parameters reasonably according to the application requirements and simulates the performance of conventional devices and superconducting devices accurately, then finishes the comparison. Simulation results show that the application of superconducting receiving technology can effectively improve the sensitivity of satellite payload. Under the condition of keeping the gain basically unchanged, the noise coefficient and suppression performance are improved after adding the superconducting receiver.
