CC2564: Effect of exceeding Bluetooth RF input/input RF level abs. max.

Muthu A

Part Number: CC2564

Hi,

I'm bit new to this wireless technology. CC2564 has a parameter 'Bluetooth RF input/input RF level'. The abs. max. rating is dBm. could any of you help me to understand this. What would happen if it's exceeded? would it damage the SoC or any internal protection will kick-in?

Thanks & Regards

Hi Muthu, this is correct. That is the maximum power level that allowed to be seen at the RF pin. Going over could damage the part. BR, Vince

Thank you Vincent.

I'm trying to understand the ways to avoid this. If the environment has too many emitters at 2.4GHz with higher power level, is there a chance that this level can go closer or higher than 10dBm (or) can it happen only under abnormal conditions? How to avoid it, if there is no inherent protection?

Thanks & Regards

Hi Muthu,

If you look at the free space path loss - the loss while signals are in the air is going to make seeing that high of RF level very hard to do. The more concern is when you are doing conducted measurements, where you'll want to make sure you attenuate the signal before it goes to our device to ensure you don't damage it.

BR,

Vince
