Follow on Google News | Saelig Introduces STD-503 2.4GHz Dual DIversity Radio TransceiverSTD-503 is a compact, true diversity embedded receiver featuring dual receiver circuits and spread specturm technology for reliable industrial wireless control.
By: Saelig Co. Inc. 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 ST-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.
