PRODUCT SPECIFICATION

430MHz-950MHz

Single Chip RF Transceiver

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.
