本文提出一种兼容NearLink 2.0的双频RF收发器，面向智能无线个人音频设备。通过优化接收机架构和发射机效率，实现了188.7dB/185.2dB的接收机FOM和30.9%的发射系统效率，性能远超传统蓝牙方案。
0-compliant dual-band RF transceiver. Compared with traditional BT/BLE counterparts, this design achieves receiver figures of merit (FOM) of 188.7dB in the 2.4GHz band and 185.2dB in the 5GHz band, exceeding the state-of-the-art by >4dB. Furthermore, it demonstrates a 30.9% 2.4GHz-transmitter-system power efficiency with exceptional EVM performance: 3.3% in 3Mb/s BT Enhanced Data Rate mode and 3.64% in 4M-16-QAM NearLink 2.0 mode (16Mb/s). Smart wireless personal audio devices (TWS earbuds, AI/AR glasses etc.) are evolving into indispensable AI gateways, where performance gains (sensing, processing, battery) and next-gen connectivity (speed, latency, stability) form a symbiotic cycle. As AI capabilities expand from health monitoring to immersive AR, these devices will necessitate
