Nordic Semiconductor's nRF905 is a single-chip radio transceiver for the 433/868/915 MHz ISM band. The nRF905 transceiver consists of a fully integrated frequency synthesiser, receiver chain with demodulator, a power amplifier, a crystal oscillator and a modulator. The ShockBurst™ 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.
