This document also describes the interfaces between WLAN/BT devices and power circuits for supporting appropriate system reference clock and power supplies from the system point of view. Figure 1 shows the system block diagram of WM-BN-BM-26_A Evaluation Kit. Doc No. Rev 1.0 Document released Date. 15/8/25 Page 5 Description WM-BN-BM-26_A User Manual 2PCB Layout Guideline DC power • Use wide traces for power supply lines. Know the maximum currents being carried on each power supply trace, and make the trace widths proportionate to the current (especially for long trace lengths). Where possible, fill large areas with copper to distribute the highest currents. These measures minimize IR drops, line inductance, and switching transients. • Use several plated via holes to connect power supply traces between layers. The number of vias used should be proportional to the current being routed. • Avoid loops in the supply distribution traces. Current-carrying loops are essentially antennas radiating electromagnetic fields that may corrupt transceiver performance or cause regulatory electromagnetic interference (EMI) test failures  Capacitor for power line, please close to module pin out  Isolate the supplies trace with ground  Spread out the LDO supply lines to reduce coupling RF General guidelines for routing RF signals of WLAN Antenna port RF signals require controlled-impedance lines to minimize mismatch losses and efficiently transfer energy from source to load. The line impedance depends upon several variables — trace width and thickness, co-planar ground spacing, height of dielectric material between the trace and ground plane(s), and dielectric constant of the PCB material. Given the PCB material selected, the geometry of the micro-strip, strip-line, or co-planar grounded waveguide (CGW) elements must be designed properly to provide the desired 50-Ω impedance. Design of micro-strip, strip-line, and CGW elements is well documented and supported in many microwave software applications The content of this document is to be treated as strictly confidential and is not to be disclosed, reproduced or used, except as authorized in writing by Universal Scientific Industrial Co., Ltd. Copyright © 2011 Universal Scientific Industrial Co. ,Ltd. 5 Doc No. Rev 1.0 Document released Date. 15/8/25 Page 6 Description WM-BN-BM-26_A User Manual Additional RF-specific PCB design guidelines include: • Keep the RF traces on the component sides (top or bottom layer) using micro-strip or CGW techniques where possible. • Screen these traces to avoid electromagnetic interference. • Use internal layers with strip-line techniques if necessary. • Maintain continuous ground below micro-strip traces, beside CGW traces, and above and below strip-line traces. • Keep traces short and direct, to minimize loss and undesired coupling. • Front-end losses increase the system noise figure — keep traces before the first gain stage as short as possible and use low-loss capacitors and inductors. • Clear internal layer (or layers) of metal. This improves micro-strip, CGW, and strip-line geometries, allowing wider traces. • Fill the areas along both sides of traces with ground to improve isolation, but provide adequate clearance to minimize co-planar capacitance and leakage. These ground-filled areas are integral to CGW designs. • Use several ground vias along both sides of the signal traces to connect RF ground-fill area…
