New SmartALPHA radio modem module

The SMARTALPHA radio modem module provides a reliable wireless communications for the transfer of data at of up to 100kbps. Their unique features of narrow band operation and user channel selection combined with excellent interference rejection make them an ideal choice for next generation applications.

The transceivers have the functions of a complete radio modem and simply require CMOS/TTL data at the transmit input and the corresponding transceiver(s) output the same data. Preamble and CRC are automatically generated and added to the RF transmission.

Operating within the 433MHz band the modules operate in user selectable channels. The SMARTALPHA can use any channel in 100kHz steps. The modules both use a crystal controlled design which provides narrow band performance which is far superior to other wideband 'SAW' based designs.

Possible applications include one-to-one and multi-node wireless links in applications including car and building security, EPOS, inventory tracking, remote industrial process monitoring and computer networking. Because of their small size and low power requirements, both modules are ideal for use in portable, battery-powered applications such as hand-held terminals.)

Applications include wireless security systems, epos terminals, sensor data logging, remote telemetry and telecommand, remote meter reading.
