26 / 37 page  Datasheet Revision 3.1 05-Jan-2022 CFR0011-120-00-FM Rev 5 26 of 36 © 2022 Renesas Electronics SC14WAMDECT SF Wireless Audio Module FINAL 7.3 PATTERN FOR PIN 79 ON THE MAIN BOARD The copper pattern for pin 79 on the main board is very important because it is part of the internal antenna of the module. It is used to extend the internal antenna for optimum RF performance. The PCB pattern shown in Figure 19 under “pads C” was used for pin 79 on the main board during module certification. 7.4 PRECAUTIONS REGARDING UNINTENDED COUPLING The SC14WAMDECT SF includes an internal antenna, so at integration on the main board precautions shall be taken in order to avoid any kind of coupling from the main board to the RF part of the module. If there is any doubt about this, a brief radio test should be performed.
