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 your
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
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. Linx offers full EMC pre-compliance testing in our
HP/Emco-equipped test center. Final compliance testing is then 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.
Note: Linx RF modules are designed as component devices that
require external components to function. The modules are intended to
allow for full Part 15 compliance; however, they are not approved by
the FCC or any other agency worldwide. The purchaser understands
that 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.
