nRF905 Product Specification
12.5 RX Reduced Power Mode
To maximize battery lifetime in application where the nRF905 high sensitivity is not necessary; nRF905
offers a built in reduced power mode. In this mode, the receive current consumption reduces from 12.5mA
to only 10.5mA. The sensitivity is reduced to typical –85dBm,
±10dB. Some degradation of the nRF905
blocking performance should be expected in this mode. The reduced power mode is an excellent option
when using Carrier Detect to sense if the wanted channel is available for outgoing data.
