CE Declaration of Conformity For the following equipment: Radicom Research Inc. Wi-Fi Module Mode(s): RB540-a, RB540-c are herewith confirmed to comply with the requirements set out in the Council (European parliament) Directive on the Approximation of the Laws of the Member States relating to Electromagnetic Compatibility of Radio and Telecom device (1999/5/CE). For the evaluation regarding this Directive, the following standards were applied: EN 300328 V1.8.1: 2012 EN 62311:2008(MPE) EN 301489-1 V1.9.
Layout Design Suggestions • General Layout Rules- All Printed Circuit Boards must comply with UL94V0 standard for flammability. Always use RoHS compliant Parts and materials. • Suggestions for Layout: 1. Do not place Power circuit, X’tal, Inductor, etc. near RF area. 2. The bigger Antenna clearance area, the better. The Antenna itself needs to stay away from any circuit or component at least 2mm. Antenna clearance area means Top and Bottom both required to be cleared. 3.
