Announcing a compact 2.4 GHz radio transceiver module for industrial applications

by donpedro

Circuit Design has announced the release of the STD-503, a 2.4 GHz radio transceiver module for embedding in industrial equipment. With the

globalization of the marketplace, there is a growing demand for industrial radio equipment that meets the requirements of a global market.
The STD-503 operates in the 2.4 GHz band available worldwide. Designed to be embedded in equipment, this compact radio transceiver module was developed for industrial applications that require stable and reliable operation. With battery operation, it achieves line of sight radio communication beyond 300 m.
To ensure highly reliable radio communication in the congested 2.4 GHz ISM band, the module uses highly noise-resistant direct-sequence spread spectrum (DSSS) modulation, as well as a true diversity receiver function for preventing signal dropout due to multi-path fading. The data interface of the STD-503 is transparent, enabling users with proprietary protocols to use them without modification. In addition, the interface offers a high degree of freedom, enabling continuous transmission of LOW or HIGH signals without restriction.
Compared with Circuit Design’s earlier models, the STD-503 is 50% smaller in volume through the use of smaller components and appropriate layout. In addition to frequency channel switching using command control inherited from earlier models, the STD-503 allows channel switching according to a preset channel plan using H/L control of dedicated channel switching pins. A maximum of 20 frequency channels can be saved in the plan.
Circuit Design developed its own ASIC with DSSS modulation and true diversity processing in order to guarantee the long-term supply of key radio components.
Circuit Design will exhibit the product at the Electronica trade fair in Munich, Germany from November 11 to 14, 2014.
