GENERAL DESCRIPTION
nRF401 is a true single chip UHF transceiver designed to operate in the 433MHz ISM
(Industrial, Scientific and Medical) frequency band. It features Frequency Shift
Keying (FSK) modulation and demodulation capability. nRF401 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. nRF401 features a
standby mode which makes power saving easy and efficient. nRF401 operates from a
single +3-5V DC supply.
As a primary application, nRF401 is intended for UHF radio equipment in compliance
with the European Telecommunication Standard Institute (ETSI) specification
EN 300 220-1 V1.2.1.
