GENERAL DESCRIPTION
nRF2401A is a single-chip radio transceiver for the world wide 2.4 - 2.5 GHz ISM
band. The transceiver consists of a fully integrated frequency synthesizer, a power
amplifier, a crystal oscillator and a modulator. Output power and frequency channels
are easily programmable by use of the 3-wire serial interface. Current consumption is
very low, only 10.5mA at an output power of -5dBm and 18mA in receive mode.
Built-in Power Down modes makes power saving easily realizable.
