A packaged silicon photonics radio-frequency (RF) synthesizer operating in the millimeter (mm-) wave band suitable for clock signal distribution in b5G/6G radio access networks is realized and experimentally characterized. The assembly include a photonic integrated circuit (PIC) acting as a frequency multiplier for a local oscillator (LO) reference at microwave frequencies and a printed circuit board (PCB) hosting a custom bias tee designed to provide a wideband matching condition over more than 6 GHz around 20GHz for the input LO signal and supporting high power levels for efficient frequency multiplication operation. Measurements performed on a 100GHz generated RF signal via five-fold multiplication of a LO wave at 20 GHz indicate a low phase noise level of -97dBc/Hz at an offset of 10kHz from the carrier with a limited excess timing jitter of less than 2fs with respect to the LO signal, making the circuit operating nearly as an ideal frequency multiplier. |
