Saelig Introduces STD-503 2.4GHz Dual Diversity Transceiver
STD-503 is a compact, true diversity embedded receiver featuring dual receiver circuits and spread spectrum technology for reliable remote control at up to 300 yards.
Saelig Company, Inc. (www.saelig.com) has introduced the STD-503, a 2.4 GHz radio transceiver module, designed to facilitate the simple embedding of wireless capabilities in industrial remote control equipment. Suitable for worldwide implementation, this compact radio transceiver module was specifically developed for industrial applications that must have stable and reliable communication for up to 300 yards with battery operation.
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 design that employs two antennas, each with its own receiving circuit, thus preventing signal dropout due to multi-path fading. The use of two antennas facing different directions to insure transmission reliability is a feature not available in most lower cost receivers.
The data interface of the STD-503 is transparent, enabling users with proprietary protocols to use them without modification. But the interface also offers a high degree of freedom, enabling continuous transmission of Low or High signals without restriction.
At only 1.6” x 1.15” x 0.22”, the STD-503 is 50% smaller than its predecessor the STD-502-R, and, in addition, the STD-503 now allows channel switching according to a preset channel plan via pin selection (up to 20 frequency channels can be saved in the plan). It uses a custom ASIC with DSSS modulation and true diversity processing in order to guarantee the long-term supply availability of key radio components. Transmitting data at up to 19.2kps, the low power operation of 10mW is achieved from a 3.3V 65mA supply. The STD-503 is already certified to FCC Part 15.247 for USA, EN 300 440 for Europe, ARIB STD-T66 for Japan, making it ready to use for the global market. Capable of operating from -20 to +65degC, the STD-503 will find application in the reliable remote control of industrial equipment, industrial telemetry, and monitoring systems.
The STD-503 is made by Circuit Design - a leading Japanese low power radio product design and manufacturing company.
