Dear Sir,
according to the datasheet, the sensetivity typical is -93dBm and a minimum is -70dBm, we would like to get reciever with a high as possible sensetivity.

1. The RX sensetivity is depend on supply voltage?
2. According datasheet typical sensetivity value is -93dBm and maximal is -70dBm . why the range is so wide?
3. If IC supplied by external DC-DC or external LDO , is matter for high performanse of sensetivity or the IC have internal filter on supply voltage?
4. could you please send us grapgh of BER/PER vs SNR?

thanks
