Study and demonstration of broadband microwave photonic performance for telecommunication satellite

In this paper, an architecture of broadband telecommunication satellite payload is introduced. On the basis of photonic technology, The payload can cope with usual requirements such as receiving and re-transmitting of inhomogeneous signals. Besides, the corresponding system for testing performance of microwave photonic of wideband telecommunication satellite is built, and parameters such as noise figure (NF), system linear property and the transmission property of the broadband signals are analyzed and demonstrated in detail. Test results are in good accordance with the theoretical prediction.
