Saelig Introduces DSSS 2.4 GHz Low Power Radio Transceiver
June 2, 2015
Fairport, NY, USA: 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
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. Additionally,
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 using 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. For detailed specifications, free technical assistance, or additional information, please
