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.

NOTES:
1) Usable band is determined by local regulations
2) The crystal frequency may be chosen from 5 different values (4, 8, 12, 16, and 20MHz) which are specified in the
configuration word, see Table 8. 16MHz is required
for 1Mbps operation.
3) Data rate must be either 250kbps or 1000kbps.
4) Antenna load impedance =
100Ω+j175Ω
5) Antenna load impedance =
100Ω+j175Ω.
Effective data rate 250kbps or 1Mbps.
6) Antenna load impedance =
100Ω+j175Ω.
Effective data rate 10kbps.
