Radio transceiver modules from Circuit Design can be used across the world, with versions for the European, Japanese, Chinese and Korean markets. A 335MHz version has just been released for the Indian market. The pin assignment in all frequency versions of the STD-302N-R is the same, so that by changing the PLL frequency, manufacturers can switch between versions according to their market. LMD-400-R, the higher grade model of the STD-302N-R, is available in FCC Part 90 and EN 300 113 compliant versions. The LMD-400-R has the same interface as the STD-302N-R, so that manufacturers can meet the requirements of the sub-GHz radio and the radio standards in each country simply by replacing the radio component. The STD-302N-R is available in 458MHz (UK), and 434 and 869MHz (Europe), 419MHz (China), 429MHz (Japan) and 447MHz (Korea) versions and have data rates of 4800bit/s for Korea, Japan and India and 9600bit/s for the other regions. The module was developed as a narrowband RF transceiver for use in industrial radio equipment. It resists to mechanical vibration and impact, and its double superheterodyne receiver circuit ensures high receiver sensitivity, says the company. Electronica: Hall A4: stand 367
