UHF Narrow Band FM Transmitter

The NTX2 transmitter and matching NRX2 receiver 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..

UHF Narrow Band FM TX & RX

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
  • Feature-rich interface (RSSI, analogue and digital baseband)
  • 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.
