Reed relays are used throughout the telecommunications industry. Some examples are modems, line switching, pager transmit/receive switching, cellular antenna switching and line sensing. Most of these applications require certification by UL, CSA, VDE, and etc. Reed relays satisfy the requirement citing that instruments must operate flawlessly, switching the AC line over millions of operations during their instrumentation life times. The transmit/receive switching circuit in cell phones and pagers switch and carry digital frequencies in the 1 - 5 GHz range where reed relays are ideally suited to carry out the switching function.
