Product Details Supplier Info More products

Radiometrix has introduced a UHF narrowband transceiver for power-constrained applications where existing single-frequency wideband UHF modules cannot deliver the range required.

Supporting data rates of up to 10kbps, the NTR2 module provides a low-power, reliable wireless data link, even in harsh industrial settings.

With an RF power output of 10dBm and a receiver sensitivity of -118dBm, its usable range can extend beyond 500m.

Available in 434.075, 434.650 and 458.700MHz versions, as well as customised options offered across the 433 (EU) and 458MHz (UK) licence-exempt bands, these transceiver products combine screening with internal filtering to minimise spurious radiation and susceptibility.

They conform to ETSI EN 300 220-3 and EN 301 489-3 standards, and have an operating temperature range of -10 to 60C.

Applications include EPOS equipment, barcode scanners, data-logging systems, industrial/commercial telemetry equipment, in-building environmental monitors, high-end security/fire alarms, DGPS systems and vehicle data up/download systems.

Due to their compact dimensions (57 x 24 x 8mm) and low levels of power consumption (20mA for transmitting and 15mA for receiving), they are particularly suitable for use in battery-powered system designs.

Pioneers of Low Power Radio – Since 1985

Based in the UK, Radiometrix is recognised as the leading global developer of ISM Band/ SRD FM low power radio modules.

We design and manufacture high-quality and cost-effective VHF and UHF radio modules that cater for the wireless needs of OEMs worldwide. Available on all major frequencies (151, 169, 173, 433, 458, 868 & 914 MHz), we offer a wide variety of modules to suit a diverse range of licence-exempt and licenced applications. The off-the-shelf modules can be customised to meet specific requirements.
