A novel self-mixing duobinary RF receiver for millimeter-wave radio-over-fiber systems

We propose a novel self-mixing duobinary RF receiver structure for 60-GHz radio-over-fiber systems, which simultaneously downconverts and decodes RF duobinary signals at Nyquist limit. Error-free transmission at 4Gb/s over 25-km SMF-28 and 4-ft wireless is demonstrated.
