Meaning
Regulatory guidance defines the specific testing protocol for evaluating the radio frequency exposure compliance of modular wireless transmitters within host devices. The kdb 996369 d02 document establishes the criteria for modular approval where the transmitter integrates into a final product without necessitating a complete new certification process. Compliance with this directive ensures that the intentional radiator maintains stable emission characteristics regardless of the host environment or the physical layout of the surrounding circuitry.
Hardware Integration
Physical assessment protocols determine whether the transmitter module retains its certified operational state when placed inside a specific host chassis. Engineers evaluate the radiated emissions and the conductive output to verify that the internal placement does not disturb the radio performance defined during the original module certification. A modular assembly must demonstrate that the proximity of external components or power supplies fails to force the transmitter outside its allowed spectral mask.
Compliance Verification
Documentation requirements mandate a clear label on the external host device that identifies the contained module by its specific identification number. This identifier confirms that the product incorporates a certified radio unit that satisfies the relevant technical rules for antenna gain, output power and harmonic filtering. Certification authorities require this transparency to ensure that the regulatory history of the transmitter remains traceable during the entire life cycle of the final commercial device.
Operational Boundary
Conditions set forth in the guidance restrict the modular approval to specific classes of host equipment that share identical radio integration characteristics. Any modifications to the antenna architecture or the radio frequency path require a new evaluation to confirm continued adherence to the emission limits. Future hardware iterations or changes in the host design require the manufacturer to assess the impact on the radio integration, as any change to the environment risks invalidating the existing modular authorization.
