6G full‑spectrum photonic chip achieves 100 Gbps
A research team in China and Hong Kong has demonstrated a thumbnail-sized 6G transceiver chip that spans nine radio bands from 0.5 to roughly 110 GHz and achieved triple‑digit Gbps data rates in the lab. Scientists led by Peking University and City University of Hong Kong reported an “all-frequency” 6G prototype fabricated on thin‑film lithium niobate, integrating functions that today require multiple RF front‑ends into a single 1.7 x 11 mm die. The device covers sub‑6 GHz, microwave, mmWave, and sub‑THz bands and demonstrated over 100 Gbps throughput under controlled conditions.
