Field-deployable, ultra-low phase noise photonic microwave oscillators

In this paper, compact, ultra-low phase noise (ULPN) photonic microwave oscillators at 10, 20, 30 and 40 GHz based on electro-optical frequency division (eOFD) are described. At 40 GHz a record-low phase noise of −153 dBc/Hz is achieved (10 kHz offset, 40 GHz carrier). The oscillators use typically 50W wall-plug power from a single 12V supply.
