UHF Narrow Band FM Transmitter
Part Number: NTX2B-434.650-10


Radiometrix launches frequency programmable Narrow Band Transmitter

Offers improved performance and greater flexibility 

Leading RF module designer and manufacturer Radiometrix Ltd, has launched a new range of highly flexible, frequency programmable, RF power adjustable radios. The new NTX2B Transmitter offers industry-leading true Narrow Band FM performance and is available on user/factory programmable custom frequencies between 425MHz and 470MHz. Superseding the popular NTX2, the new transmitter offers greater stability and improved performance due to VCTCXO reference. The NTX2B provides users with the ability to dynamically re-program the module via microcontroller UART to other channel frequencies in the band or store new frequency/power settings on EEPROM.
 
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.
