NTX2/NRX2

UH F N a r r o w Ba n d FM TX & RX

The NTX2 transmitter and NRX2

receiver offer a low power, reliable

data link in Radiometrix SIL

standard pin out and foot print. This

makes the NTX2/NRX2 pair ideally

suited to those low power applications

where

wideband

existing

UHF

single

frequency

have

modules

insufficient range.

Features

•

Conforms to ETSI EN 300 220-3 (radio) and EN 301 489-3 (EMC)

Standard frequencies: 434.075MHz, 434.650MHz and 458.700MHz

Custom frequencies available in 433MHz (EU) and 458MHz (UK) band

Data rates up to 10kbps

Usable range over 500m

25kHz Channel spacing

Longer range compared to Wide Band FM modules

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.
