Low-power receiver allows always-on speed in telemetry systems

2nd February 2016

Posted By Paul Boughton


Radiometrix’ latest RX1L narrowband receiver consumes less than 1mA, allowing ‘always-on’ functionality in energy-limited solar or battery-operated equipment without excessively draining the power source and limiting operation.

Measuring 59mm x 38mm, and only 7mm high, the RX1L is suitable for space-constrained applications such as data logging, industrial telemetry, smart-building controllers, security or fire-safety. Its industry-standard footprint and pin-out, simplify design-in to new equipment or upgrading existing designs that currently use other receivers. The wide supply-voltage range of 3.1-9V DC means the device is easily powered from various standard battery voltages.

The RX1L is a single-channel receiver available on 151.300MHz, 169.4125MHz, and 173.225MHz frequencies as standard. Other frequencies are available by special request. As a narrowband device it is suitable for long-range applications at bit rates up to 5kbps, aided by high receive sensitivity of up to -120dBm for 12dB SINAD.

The module is fully shielded, enjoying high immunity to external interference, and is compliant with ETSI EN 300 220-2 (radio) and EN 301 489-3 (EMC) standards.

Users can evaluate new projects based on the RX1L, using the NBEK evaluation platform and xx2M carrier/adapter for the receiver module, available now from Radiometrix.
