Circuit Design is a leading supplier of low power radio modules. Circuit Design specialises in the design and manufacture of embedded transmitter, receiver, transceiver and RF modems in the license-exempt, low power radio band (Short Range Devices in Europe). Low-power, narrow-bandwidth and discrete component designs are targeted at long-range, battery-powered industrial applications. These serve well in fields such as telecommand, telecontrol, telemetry, alarms, and security, and for all kinds of wireless data transmission where high reliability is required.
