一、nRF2401芯片概要
nRF2401 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.
nRF2401是一款单片型射频收发芯片，其工作于世界通用的2.4-2.5GHz的ISM频段。芯片内置频率合成器、功率放大器、晶体振荡器和调制器等功能模块。通过3线串行接口，可以很容易的利用程序对输出功率和通信频道进行配置。该芯片功耗非常低，以-5dBm 的功率发射时，工作电流只有10.5mA，另接收模式时工作电流只有18mA。内置的掉电模式使得节能变的更容易实现。
