HF Narrow Band FM Receiver


The 10kHz channel NBFM NTX0 transmitter and NRX0 receiver operate on the license exempt 27MHz SRD HF allocation. These modules offer a low power, reliable data link in a Radiometrix SIL standard pin out and foot print. This makes the NTX0/NRX0 pair ideally suited to those low power applications where existing single frequency wideband UHF modules have insufficient range, and in parts of the world where other frequency bands are not appropriate

Features of NTX0

  • Conforms to ETSI EN 300 220-3 (radio) and EN 301 489-3 (EMC) and FCC 95.201-95.225
  • Standard frequency: 27.095MHz
  • Data rates up to 5kbps
  • Usable range over 1km @ 10mW
  • 10/12.5kHz Channel spacing
  • Feature-rich interface (RSSI, analogue and digital baseband)
  • Longer range compared to Wide Band FM modules

Applications of NTX0

  • Radio Control (R/C) Radio Service under FCC Part 95 subpart C
  • Radio model control
  • Telemetry and telecommand
  • Wireless door entry systems
  • Simple On/Off switching
  • In-building environmental monitoring and control
  • Security and fire alarms
  • Vehicle/machinery controls

Technical Summary
