NTX2B

UHF Narrow Band FM Transmitter

NTX2B transmitter

Frequency:425MHz - 480MHz

Available for licence-exempt operation in the 433MHz (EU) and 458MHz (UK) bands, the NTX2B module combine effective screening with internal filtering to minimise spurious radiation and susceptibility thereby ensuring EMC compliance.

It can be used in existing low data rate (<10kbps) applications where the operating range of the system using TX2 transmitter and RX2 receiver need to be extended. They are particularly suitable for point-to-point and point-to-multipoint wireless links where longer ranges are required at low data rates.
