Achieving a Successful RF Implementation
Adding an RF stage brings an exciting new
dimension to any product. It also means
that additional effort and commitment will be
needed to bring the product successfully to
market. By utilizing pre-made RF modules
the design and approval process is greatly
simplified. It is still important, however, to have
an objective view of the steps necessary to
ensure a successful RF integration. Since the
capabilities of each customer vary widely, it is
difficult to recommend one particular design
path, but most projects follow steps similar to
those shown in Figure 46.
In reviewing this sample design path, you
may notice that Linx offers a variety of
services (such as antenna design and FCC
pre-qualification) that are unusual for a
high-volume component manufacturer. These
services, along with an exceptional level
of technical support, are offered because
we recognize that RF is a complex science
requiring the highest caliber of products and
support. “Wireless Made Simple” is more than
just a motto: it’s our commitment. By choosing
Linx as your RF partner and taking advantage
of the resources we offer, you will not only
survive implementing RF, you may even find the
process enjoyable.

Helpful Application Notes From Linx
It is not the intention of this manual to address in depth many of the issues
that should be considered to ensure that the modules function correctly
and deliver the maximum possible performance. As you proceed with your
design, you may wish to obtain one or more of the following application
notes which address in depth key areas of RF design and application of
Linx products. These applications notes are available online at
www.linxtechnologies.com or by contacting the Linx literature department.
