UWB Base Station Positioning System PCB Assembly: High-Precision Core for Centimeter-Level Positioning Empowering Industry Transformation
The PCB assembly for UWB base station positioning systems serves as the cornerstone for constructing high-precision indoor/outdoor positioning networks. Leveraging a 16-layer arbitrary-stage HDI (3+N+3) stacked structure with LTCC RF substrate (εr=7.8±0.1), it achieves ±1.5% impedance control at 10.6GHz (vs. industry benchmark ±5%). Core materials include Rogers RO4830™ (Df=0.0023 @10GHz) and Arlon AD350A thermal adhesive (1.5W/mK), with CTE matching ensuring Δα < 2ppm/℃. Advanced differential routing with impedance compensation delivers a common-mode rejection ratio (CMRR) ≥65dB, certified under IEEE 802.15.4z-2024.
Technical Highlights
