The pin assignment is the same across all frequency versions, so by changing the PLL frequency program, manufacturers can upgrade to the next version according to their market. The LMD-400-R, the higher-grade model of the STD-302N-R, is available in FCC Part 90 and EN 300 113 compliant versions. Furthermore, the LMD-400-R has the same interface as the STD-302N-R. Using this common platform, manufacturers can meet sub-GHz radio requirements and radio standards in each country simply by replacing the radio component.
The STD-302N-R was developed as a narrowband radio frequency transceiver for use in industrial radio equipment. It is resistant to vibration and shock, and its dual superheterodyne receiver circuitry ensures high receiver sensitivity. Operating in a narrow band with high selectivity, the STD-302N-R provides highly reliable communication even in applications where multiple devices are used simultaneously. Designed for high performance with the flexibility of discrete components, the STD-302N-R ensures a stable, long-term product supply. This concept, combined with stable, high-quality performance, is highly valued by manufacturers worldwide.
