A technical paper titled “Compact, broadband nanoacoustic passband filters for future 5G and 6G cellular radios” was published by researchers at Northeastern University.
Abstract:
“In recent years, the proliferation of mobile communications has deepened global connectivity. The growing demand for faster data rates has intensified the demand for higher carrier frequencies. 5G sub-6 GHz and mmWave spectrum The range between 7 and 20 GHz provides a good trade-off between network capacity and coverage and constitutes an untapped range for 5G and 6G applications. By exploiting micro-to-nano scaling, we propose a technology platform that can provide CMOS-compatible, on-chip multifrequency, low-loss, wideband, compact filters for cellular radios operating in this range of resonance. The results demonstrate for the first time a low insertion loss bank of seven nanoacoustic passband filters in the We demonstrate less than dB of loss, which enables the production of filters and duplexers for the next generation of mobile phones operating in the X-band and beyond.”
