nRF903 is a true single chip multi-channel UHF transceiver designed to operate in the unlicensed 433MHz, 868MHz and 915MHz ISM-/LPRD- (Industrial Scientific Medical / Low Power Radio Device) bands. Multi-channel operation, excellent receiver selectivity and sensitivity, high bandwidth efficiency and blocking performance make the nRF903 suitable for wireless links where high reliability is a key requirement. The device features GFSK (Gaussian Frequency Shift Keying) modulation and demodulation capability at an effective bit rate of 76.8kbit/s in 153.6kHz channel bandwidths. Transmit power can be adjusted to a maximum of 10dBm which is available for all frequency bands and channels. Antenna interface is differential and suited for low cost PCB-antennas. All necessary configuration data is programmed by a 14-bit configuration word via a Serial Peripheral Interface (SPI). nRF903 operates from a single +3V DC supply and features power down- and standby-modes which makes power saving easy and efficient.
