Multi-channel receiver targets social-alarm applications

Radiometrix has released the multi-channel COR3-869-5-SAL receiver, the first in a new range of Category 1 compliant radio receiver modules. The COR3 receiver complies to the new EN300-220-2 V2.3.1 (2010-02) Category 1 standard for receivers (formerly Class 1).
 
Available on the licence-exempt European 869.2-869.250MHz sub-band for social alarms and also custom frequencies between 865-870MHz, the 32-channel COR3 offers superior sensitivity, interference rejection and stability. Category 1 performance is required in Europe for short-range communication devices for social alarm applications.

When paired with the new EST3 low power transmitter, a wireless data link with a range of over 500m can be achieved. The 25kHz channel spacing narrowband receiver has a receive sensitivity of -120dBm typical (for 12 dB SINAD) and incorporates a wide range RSSI (received signal strength indicator).

The new range of Category 1 receivers offers developers flexibility through consistent pinouts, compatible with Radiometrix's existing range of SIL package radios. Various levels of multi-channel operation are possible; parallel, serial channel selection, Packet Link for Telemetry or encoder/decoder for telecommand and custom firmware.

With its compact dimensions (57 x 26 x 9mm), Category 1 compliance, CE marking and low power requirements (current consumption is typically 25mA), the COR3 is well suited to low power wireless applications such as nurse-call systems, monitoring and control, high-end alarms and industrial applications including heavy vehicle/machine remote controls.
