Part Number: CC2591
Other Parts Discussed in Thread: CC2520
Hello,
we are using a CC2520 zigbee transmitter in combination with a CC2591 range extender for our product. While carrying out the EMI testing, we find that there exists a 2.2GHz peak along with our intended 2.4GHz signal. The magnitude of the signal is comparable to the 2.4GHz signal. We are using a test software to transmit every 10-100ms and we are able to set the channel and transmit power. What we observe is that the channel and transmit power of our target signal at 2.4GHz is behaving as per our setting, but the unintended signal at 2.2GHz remains unchanged in its frequency as well as power for any setting.
I am looking to find the root cause and potential solutions for this. It would be very helpful if you could support.
Thank you.
Regards,
Akhil
