Zusammenfassung:RF-photonic approaches have been evaluated for distributing electrically generated local oscillator (LO) signals as well as for performing frequency conversion with optically generated LO signals. For high-fidelity distribution of electrically generated signals, a switched RF photonic link was measured to have a residual phase noise of -145 dBc/Hz at an offset of 10 kHz from the X-band carrier. The switch isolation was better than 80 dB. For efficient frequency conversion with the RF-photonic approach, a relative conversion loss of 6.2 dB was measured for an LO modulation index of 0.97.
