GENERAL DESCRIPTION
nRF0433 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. nRF0433 operates at bit rates
up to 9600 bit/s. Transmit power can be adjusted to a maximum of 10dBm. It features
a differential antenna interface and an internal transmit/receive switch. nRF0433
operates from a single +5V DC supply.
As a primary application, nRF0433 is intended for design of UHF transceivers in
compliance with the European Telecommunication Standard Institute (ETSI)
specification EN 300 220-1 V1.2.1.
