GENERAL DESCRIPTION
nRF402 is a true single chip UHF transmitter designed to operate in the 433MHz ISM
(Industrial, Scientific and Medical) frequency band. It features Frequency Shift
Keying (FSK) modulation capability. nRF402 operates at data rates up to 20kbits/s.
Transmit power can be adjusted to a maximum of +10dBm. Antenna interface is
differential and suited for low cost PCB antennas. nRF402 operates from a single 3V
DC supply and has a standby mode which makes power saving easy and efficient.
As a primary application, nRF402 is intended for UHF radio equipment in compliance
with the European Telecommunication Standard Institute (ETSI) specification
EN 300 220-1 V1.2.1.
