GENERAL DESCRIPTION
nRF905 is a single-chip radio transceiver for the 433/868/915 MHz ISM band. The transceiver consists of a fully integrated frequency synthesiser, receiver chain with demodulator, a power amplifier, a crystal oscillator and a modulator. The
ShockBurst(TM) feature automatically handles preamble and CRC. Configuration is easily programmable by use of the SPI interface. Current consumption is very low, in transmit only 11mA at an output power of -10dBm, and in receive mode 12.5mA. Built in power down modes makes power saving easily realizable.
