nRF403 is a true single chip UHF transceiver designed to operate in the 433MHz ISM (Industrial, Scientific and Medical) and 315 MHz frequency band. It features Frequency Shift Keying (FSK) modulation and demodulation capability. nRF403 operates at bit rates up to 20kbit/s. Transmit power can be adjusted to a maximum of 10dBm. Antenna interface is differential and suited for low cost PCB antennas. nRF403 features a standby mode which makes power saving easy and efficient. nRF403 operates from a single +3 V DC supply. As a primary application, nRF403 is intended for UHF radio equipment in compliance with the European Telecommunication Standard Institute (ETSI) specification EN 300 220-1, the US Federal Communications Commission (FCC) standard CFR47 and Weak Power Radio in Japan.
