RTX-868-NB is a SMD multichannel narrow band transceiver operating in 868.00 - 868.60 MHz band
allowing long distances with very low power consumption.
The device is suitable for battery powered sensors requiring very low power consumption, in particular for
smoke and fire detection applications.
A typical scenario is an alarm sensor network in which each node is able to detect an alarm.
When a device detects the alarm, it activates a node local warning and it sends a broadcast RF message to
notify the alert to all the other devices of the network.
RTX-868-NB has also the possibility to locally deactivate the alarm and notify the deactivation to all the
devices of the network.
It is furthermore possible to test the link radio between two devices, an useful feature during the network
installation.
For security reasons each radio communication is encrypted with AES 128 algorithm.
Main Features
Reduced dimensions ( 20 x 20 x 2.5 mm )
40mW max RF output power
Sensitivity -115dBm
Blocking category 1
10uA average current consumption
Encrypted data transmission
