Ultra Low Phase Noise Photonic Microwave Oscillators
hQphotonics designs and produces ultra low phase noise (ULPN) photonic microwave oscillators and synthesizers, spun out of Caltech's Applied Physics Department. Their electro-optical frequency division (eOFD) oscillators cover 8–40 GHz with phase noise 30 dB better than best-in-class PLL-based alternatives. Products serve defense and aerospace, coherent communications, quantum computing, 5G, and test and measurement markets.
