Selectivity Bluetooth Low Energy (Typical performance; wanted signal at channel 2440 MHz and -67 dBm input level)
2 Desired signal level at PIN = -67 dBm. One interferer is used, having equal modulation as the desired signal. The input power of the interferer where the sensitivity equals BER = 0.1% is presented.
