Abstract This paper presents a phased-array-inspired RF signal processor for ultra-broadband spectrum sensing. The proposed architecture exploits the bandpass response resulting from the constructive and destructive interference of a programmable dispersion-engineered array, implemented with broadband true-time delay lines and programmable phase shifters. The proposed design is fabricated in a 22nm FDX process, achieving a measured scanning range of 2 to 32GHz with a power consumption of 101mW. Frequency Range 3 (FR3), which covers the frequency range from 7.125GHz to 24.25GHz, is a strong candidate for 6G wireless communications due to a favorable coverage-capacity trade-off. To fully utilize the FR3 spectrum with existing mobile services at sub-6GHz and the FR2 mm-wave spectrum, innovative temporal and spatial spectrum sharing is essential across the entire frequency band, requiring energy-efficient, ultra-broadband, real-time
