GENERAL DESCRIPTION
nRF2402/nRF2402G is a single-chip radio transmitter for the world wide 2.4 - 2.5 GHz ISM
band. The transmitter consists of a fully integrated frequency synthesizer, a power amplifier,
a crystal oscillator and a modulator. Output power and frequency channel is easily
programmable by use of the 3-wire interface. Current consumption is very low, only 10 mA
at an output power of -5dBm. Built-in ShockBurst™ and Power Down modes makes power
saving easily realizable.
