Description

The standard NTX2B version is a 10mW 25kHz Narrow bandTransmitter with data rates up to 10kbps and is available on 434.075MHz, 434.650MHz European SRD
frequencies and 25mW on 458.700MHz for the UK. The NTX2B is also available with 12.5kHz or 20kHz channel spacing for licensed US FCC Part 90 or legacy
European Telemetry/Telecommand bands. The NTX2B features an internal LDO voltage regulator which enables the transmitter to be operated down to 2.9V
and up to 15V voltage supply at a nominal current consumption of 18mA and less than 3uA in power-down mode, which can be enabled within 5ms. NTX2B
can transmit both digital and 3V pk-pk analogue signals. Offering greater range than wideband modules, the transmitter can be paired with the new NRX2B
receiver for a usable range of over 500m, ideal for performance critical low-power wireless applications including security, sensor networks, industrial/commercial
telemetry and remote control.
