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.
• True single chip GFSK transceiver in a small
32-pin package (32L QFN 5x5mm)
• ShockBurst™ mode for low power operation
• Power supply range 1.9 to 3.6 V
• Multi channel operation – ETSI/FCC
Compatible
• Channel switching time <650µs
• Extremely low cost Bill of Material (BOM)
• No external SAW filter
• Adjustable output power up to 10dBm
• Carrier detect for "listen before transmit"
