Integrating RF modules into IoT products isn’t as simple as plugging in a certified module. The REDCA TGN 01 document provides essential guidance for manufacturers, emphasizing that both the RF module and the final product must undergo compliance testing.
Even if your module is pre-certified, it doesn’t mean your product is automatically compliant. This document is essential for anyone integrating RF modules, as it outlines the necessary steps to avoid regulatory issues, from conformity assessments to technical documentation.
The Importance of REDCA TGN 01 for Integrators
The REDCA TGN 01 document is a lifeline for manufacturers and integrators navigating the complex regulatory environment. It helps to avoid costly mistakes by ensuring the entire product complies with the Radio Equipment Directive (RED) 2014/53/EU—not just the RF module.
Why does this matter?
Even a compliant RF module can become non-compliant when integrated into a product due to interference, shielding, or reflections caused by the host product. This is why testing the final product, not just the module, is crucial.
The document sets the foundation for:
- Conformity Assessment: Testing the final product for safety, EMC, and radio performance after module integration.
- Documentation: Maintaining clear, comprehensive technical files for the RF module and the final product.
- Risk Assessment: Evaluating whether the module’s original test data applies to your final product or if additional testing is necessary.
What’s Involved in the Conformity Assessment?
Conformity assessment is not optional—it’s mandatory for any product that incorporates an RF module. The assessment must verify that the final product complies with RED’s safety, EMC, and radio performance requirements.
RF Module Conformity
The module must be tested for safety, electromagnetic compatibility (EMC), and radio performance under RED Article 3. The module’s documentation should specify the environment in which it was tested, including:
- Antenna type
- Operating temperature range
- Input voltage
- Installation instructions
Final Radio Product Conformity
After integrating the RF module, the final product essentially becomes a new product, requiring further testing. Even though the module itself may be certified, the final product must still undergo conformity assessment to meet RED standards for:
- Safety (Article 3.1a): Reassessing the safety of the final product.
- EMC (Article 3.1b): Ensuring the electromagnetic compatibility of the module within the host product.
- Radio Performance (Article 3.2): Re-testing the module in its final configuration to verify proper performance.
Real-Life Scenarios from REDCA TGN 01
To illustrate the importance of testing both the module and final product, here are a few practical examples from the REDCA TGN 01 document:
1. Plug-in Devices
Let’s say you’re integrating a USB RF module into a laptop. If the module can be easily removed, no further assessment is required. However, if the module is soldered into the product permanently, it becomes part of the final product and must be reassessed for safety, EMC, and radio performance.
2. Modules with Antennas
Imagine an RF module with an integrated antenna installed inside a metal case. While the module might perform well on its own, reflections or shielding inside the case could alter its radio emissions. The entire product needs to be retested to ensure compliance.
3. Soldered Module Chips
Consider a case where an RF module is soldered directly onto a circuit board. This could cause interference with other components, requiring the final product to undergo full testing for safety, EMC, and radio performance.
Why This Matters
The REDCA TGN 01 document is essential for manufacturers looking to avoid costly compliance mistakes. If you ignore the guidance, you could face failed compliance tests, delayed product launches, and even potential recalls.
But this isn’t just about regulatory compliance—it’s about ensuring your product is safe, functional, and ready for market. Regulatory testing is a safeguard, not just a checkbox, ensuring that your product performs as expected and doesn’t put users at risk.
