Circuit Design has announced the release of the MU-D1-R 915MHz, an embedded low-power radio transceiver modem for industrial use that complies with US FCC Part 15.247.

Designed to be embedded in equipment, the MU-D1-R radio modem was developed for industrial applications that require stable and reliable operation.

It has a low consumption current, so it achieves line-of-sight radio communication beyond 300m with battery operation.

Besides using noise-resistant direct-sequence spread spectrum (DSSS) modulation, the modem has a true diversity receiver function with two receiver circuits for preventing signal dropout due to multipath fading.

This is said to ensure stable and reliable radio communication in the congested 902 to 928MHz ISM band, which is used by various types of equipment.

With 20 frequency channels, it can be used in several radio systems.

The modem operates at low power (55mA/5mW when transmitting and 58mA when receiving) and, with its small size (36mm x 26mm x 8mm), it can be built into units that require battery operation.

In addition to the CDP series transmitter and receiver modules and STD/LMD series transceiver modules, Circuit Design offers the MU series radio modem with a built-in wireless protocol to enable the input/output of data with simple commands.

With its built-in CPU, the MU series performs wireless-specific high frequency control for UART communication with an external microcomputer.

As a result, it can shorten development time and reduce the number of product parts.

The built-in protocol allows for networking and, besides applications that require reliability and real-time control such as industrial remote control, it is expected to be used in a wide range of low-power industrial applications such as monitoring systems where battery operation is required.

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.
