8 Experts on Overcoming Challenges of RF Solution Design 16
When you use any RF component, ensure that those components will be available for the
life of your product. Any component changes will require a recertification of the device if
the component is within the RF path, which is time consuming and costly. Wireless modules
are lower risk than an RF circuit you build yourself because the wireless module is just one
component, whereas the RF circuit contains many components, any one of which could
become unavailable. Wireless chips and modules can become obsolete, too, and then you
not only need to replace the part but update the software. Your choices depend on the
product and the market. In our case, we like to ensure that RF components will be available
for a minimum of ten years.
