Telecommunications

The world is becoming an increasingly interconnected place, and telecommunications products and systems help to enable this connectivity. The smartphones that are replacing PCs, laptops, cameras, and even GPS systems are crammed with electronic components for voice communications, texting, email, web browsing, social media interaction, navigation, and imaging. Supporting are these functions are the earthbound, airborne, and underwater systems that comprise the telecommunications infrastructure: base stations, transmission towers, satellites, submarine communications cables, modems, line cards, and more, all of which require electronic components.

For an xDSL network, each subscriber needs a so-called "Splitter" to divide the narrowband signals of the POTS (Plain Old Telephone Service) or ISDN (Integrated Services Digital Network) and the wideband xDSL signals. This is done by a combination of tight-tolerance low-pass and high-pass filters.
