I have been designing with the Lynx CMD-KEY5 and FCTN-DEC1 Tx/Rx modules for clients who want simple Part 15 RF designs but don't want to front the time and money for FCC certification. These are(were) FCC pre-qual'd and could be just integrated without needing new FCC certifications.
However, Lynx, in their infinite wisdom is ditching the FCTN-DEC1 line and telling us to use the "KH" line of chips, which are a little cheaper and better performance. However, the FCC cert looms large on the horizon. Getting a "cert of conformance" or new FCC cert is thousands of $$ and takes months to live through. That is enough to kill any interest in a design for my low volume clients.
So...
Can anyone recommend a USA available Tx/Rx Part 15, FCC pre-certified product that uses a keyfob or other handheld transmitter (which Lynx still provides) and a FCC pre-certified (with conformance letter) receiver which can be integrated into an OEM microcontroller device? I've not been able to find one that is simple control line out with 5-8 outputs anywhere.
sigh, I REALLY don't want to deal with FCC certs, and I can't afford to roll my own device as an OEM module with FCC either.
Thanks all, DLC
