NRF903 General Description
nRF903 is a true single chip multichannel UHF transceiver designed to operate in the unlicensed 433MHz, 868MHz and 915MHz LPRD- (Low Power Radio Device) bands. It features both GMSK (Gaussian Minimum Shift Keying) and GFSK (Gaussian Frequency Shift Keying) modulation and demodulation capability at an effective bit rate of 76.8kbit/s for 153.6kHz channel bandwidths. Transmit power can be adjusted to a maximum of 10dBm. 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). Multi-channel operation and excellent receiver selectivity makes nRF903 suitable for wireless links where high-reliability is a key requirement.
nRF903 operates from a single +3V DC supply and features power down- and standby-modes which makes power saving easy and efficient.
As a primary application, the transceiver is intended for UHF radio equipment in compliance with the European Telecommunication Standard Institute (ETSI) specification EN 300 220-1 V1.2.1. and the US Federal Communications Commission (FCC) standard CFR47.
