【Abstract】In order to comply the regulations and standards of European market，telematics box（T-Box）products need to be CE-RED certified. Excessive radiated spurious emission（RSE）is one of the common problems during the certification. This article provides detailed analysis and countermeasure methods on RSE. It also gives recommendations on RF switch selection and application on actual product.

【Key words】CE-RED;telematics box（T-Box）;radiated spurious emission（RSE）;RF switch
