A hybrid optoelectronic synthesizer is developed that combines simplified optical frequency division with direct digital synthesis to generate tunable, low-phase-noise microwaves across the X-band. This approach also achieves high frequency stability while reducing the size, weight and power demands, paving the way for chip-scale photonic microwave sources.
