Wi-Fi&Bluetooth Module Series 3.8.4. Reference Design of RF Layout For user’s PCB, the characteristic impedance of all RF traces should be controlled to 50 Ω. The impedance of the RF traces is usually determined by the trace width (W), the materials’ dielectric constant, the height from the reference ground to the signal layer (H), and the spacing between RF traces and grounds (S). Microstrip or coplanar waveguide is typically used in RF layout to control characteristic impedance.
Wi-Fi&Bluetooth Module Series Figure 12: Coplanar Waveguide Design on a 4-layer PCB (Layer 4 as Reference Ground) In order to ensure RF performance and reliability, the following principles should be complied with in RF layout design: Use an impedance simulation tool to accurately control the characteristic impedance of RF traces to 50 Ω. The GND pins adjacent to RF pins should not be designed as thermal relief pads, and should be fully connected to ground.
