NRX2

UHF Narrow Band FM Receiver

Frequency:Standard: 434.075MHz, 434.650MHz and 458.700MHz

The NRX2 receiver and matching NTX2 transmitter offer a low power, reliable data link in a Radiometrix SIL standard pin out and foot print. This makes the NTX2/NRX2 pair ideally suited to those low power applications where existing single frequency wideband UHF modules have insufficient range.

Available for licence-exempt operation in the 433MHz (EU) and 458MHz (UK) bands, the NTX2 & NRX2 modules combine effective screening with internal filtering to minimise spurious radiation and susceptibility thereby ensuring EMC compliance. They 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. Applications include sensor nodes, EPOS and inventory tracking, remote industrial process monitoring, telemetry, telecommand and telecontrol. Because of their small size and low power consumption, both modules are ideal for use in battery-powered portable applications such as handheld terminals.
