Breakthrough in 19GHz Direct RF Sampling – Transforming Satellite Communication & Radar Systems
2025-09-11
Direct RF sampling enables high-frequency signals to be captured directly, simplifying system design, enhancing reliability, and reducing power consumption – the “crown jewel” of signal processing.
Recently, China launched its first 4-channel, 12-bit, 40GSPS high-speed RF direct-sampling ADC, featuring a 19GHz analog input bandwidth – a milestone that positions China at the forefront of high-end RF technology.
Why 19GHz Matters
The 19GHz bandwidth directly covers C, X, Ku, and parts of K-band signals, offering true “RF direct sampling freedom.” This allows satellite communications, millimeter-wave radar, and electronic reconnaissance systems to improve performance while reducing size and cost.
Direct RF sampling eliminates the need for multiple frequency conversions, simplifying system architecture, boosting reliability, and lowering power consumption.
Industry Impact
This breakthrough is significant for communications, defense, and aerospace sectors. With 5G-Advanced deployment and growing demand for satellite-connected devices, RF front-end design faces unprecedented challenges – and 19GHz direct sampling provides a leading-edge solution.
Looking Ahead
Achieving 19GHz bandwidth demonstrates domestic capability in high-end RF design and manufacturing, fueling industry innovation. China’s RF chip sector is poised for global growth, supporting national security and the digital economy, and enabling broader applications in satellite communication, radar, and electronic reconnaissance.
