Recently, our company's independently developed TQSRO-C50 sapphire oscillator achieved a major technological breakthrough. Following comprehensive optimization of the oscillator system—particularly enhancements to the control circuit—its output 10GHz signal phase noise reached below -155dBc/Hz@10kHz. This not only sets a new performance benchmark for engineered sapphire oscillators but also signifies a critical advancement in China's capabilities for generating ultra-low phase noise signals.

Phase noise, as a core metric for evaluating the spectral purity of signal sources, directly determines the performance ceiling of systems such as communications, radar, and precision measurement. The sapphire oscillator's breakthrough of -155 dBc/Hz@10kHz at 10GHz represents a significant improvement over its first-generation product released in 2023, signifying a reduction in the amplitude of rapid random fluctuations in signal frequency by nearly an order of magnitude.

Advancing the phase noise of 10GHz signals below -155 dBc/Hz is the culmination of our team's years of dedicated R&D. This represents not merely a numerical improvement but our capability to deliver unprecedented signal quality for the most demanding applications," stated the project's technical lead.

With the accelerated advancement of low-altitude detection, satellite network technology development, and the quantum information industry, market demand for ultra-low phase noise oscillators is rapidly escalating. Tianqiong Electronics' technological breakthrough not only provides critical component support for China's high-end manufacturing sector but will also drive performance leaps in low-altitude operations, communications, scientific research, and other fields.
