Bit 7 – 1:
RF_CH#: Sets the frequency channel the nRF2401A operates on.
The channel frequency in transmit is given by:
Channel_RF = 2400 MHz + RF _ CH # ⋅1.0 MHz
RF_CH #: between 2400MHz and 2527MHz may be set.
The channel frequency in data channel 1 is given by:
Channel_RF = 2400 MHz + RF _ CH # ⋅1.0 MHz (Receive at PIN#8)
RF_CH #: between 2400MHz and 2524MHz may be set.
NOTE:
The channels above 83 can only be utilized in certain territories (ex: Japan)
The channel frequency in data channel 2 is given by:
Channel_RF = 2400 MHz + RF _ CH # ⋅1.0 MHz +8MHz (Receive at PIN#4)
RF_CH #: between 2408MHz and 2524MHz may be set.
