RE: Understanding Receiver Sensitivity Relationship to Antenna

Ok thanks, I think I understand now. The chip itself is claiming that the final received power level required for reliable communication is -96dBm (conducted sensitivity), but what the actual received strength ends up being is dependent on the antennas performance. I don't know why I confused the two, but thanks for clearing that up.

Hi,

The RX sensitivity spec is conducted sensitivity, i.e. the signal level on the input of the matching network that yields the specified BER. A radiated sensitivity (TRS or TIS) would refer to the signal strength recevied by the antenna, and take the antenna gain into the mix. In a practical setup the antenna does have an impact on the range, both for transmitter and receiver.

Whatever 3rd party vendors do I do not know, but the conducted sensitivity remains the same provided they have done the layout properly. It sounds as they are also providing the conducted sensitivity.

Best regards,

Andreas
