Wideband Microwave Phase Noise Analyzer Based on an All-Optical Microwave I/Q Mixer
Journal of Lightwave Technology(2018)
摘要
Digital phase demodulation can greatly simplify the calibration of microwave phase noise analyzers (PNAs) based on frequency discriminators, and avoid the use of feedback loops, but the required microwave in-phase and quadrature (I/Q) mixer always has a small operational bandwidth, leading to a limited phase noise measurement frequency range. In this paper, a novel photonic microwave PNA based on ...
