Regulatory Considerations

When working with RF, a clear distinction must be made between what

is technically possible and what is legally acceptable in the country where

operation is intended. Many manufacturers have avoided incorporating RF

into their products as a result of uncertainty and even fear of the approval

and certification process. Here at Linx, our desire is not only to expedite the

design process, but also to assist you in achieving a clear idea of what is

involved in obtaining the necessary approvals to legally market a completed

product.

For information about regulatory approval, read AN-00142 on the Linx

website or call Linx. Linx designs products with worldwide regulatory

approval in mind.

In the United States, the approval process is actually quite straightforward.

The regulations governing RF devices and the enforcement of them are

the responsibility of the Federal Communications Commission (FCC). The

regulations are contained in Title 47 of the United States Code of Federal

Regulations (CFR). Title 47 is made up of numerous volumes; however,

all regulations applicable to this module are contained in Volume 0-19.

It is strongly recommended that a copy be obtained from the FCC’s

website, the Government Printing Office in Washington or from your local

government bookstore. Excerpts of applicable sections are included

with Linx evaluation kits or may be obtained from the Linx Technologies

website, www.linxtechnologies.com. In brief, these rules require that any

device that intentionally radiates RF energy be approved, that is, tested for

compliance and issued a unique identification number. This is a relatively

painless process. Final compliance testing is performed by one of the many

independent testing laboratories across the country. Many labs can also

provide other certifications that the product may require at the same time,

such as UL, CLASS A / B, etc. Once the completed product has passed,

an ID number is issued that is to be clearly placed on each product

manufactured.

Note: Linx RF modules are designed as component devices that require

external components to function. The purchaser understands that

additional approvals may be required prior to the sale or operation of

the device, and agrees to utilize the component in keeping with all laws

governing its use in the country of operation.

Questions regarding interpretations of the Part 2 and Part 15 rules or the

measurement procedures used to test intentional radiators such as Linx RF

modules for compliance with the technical standards of Part 15 should be

addressed to:

International approvals are slightly more complex, although Linx modules

are designed to allow all international standards to be met. If the end

product is to be exported to other countries, contact Linx to determine the

specific suitability of the module to the application.

All Linx modules are designed with the approval process in mind and thus

much of the frustration that is typically experienced with a discrete design is

eliminated. Approval is still dependent on many factors, such as the choice

of antennas, correct use of the frequency selected and physical packaging.

While some extra cost and design effort are required to address these

issues, the additional usefulness and profitability added to a product by RF

makes the effort more than worthwhile.
