Photonic downconversion and microwave to digital subsystems

Summary form only given, as follows. Frequency downconversion is an essential part of many rf systems and is particularly important in microwave-to-digital systems. In this paper, system design issues are discussed to take full advantage of recently available photonic technology including photonic downconversion and downsampling. These concepts are discussed and demonstrated within the context of two promising photonic microwave to digital architectures.
