AR, with headquarters in Souderton, PA, is marking its 40th anniversary. The company’s modest beginnings, in the form of a new test amplifier, started out in the basement of Donald “Shep” Shephard, who remarked that having begun in the basement that there was no place to go but up. Formerly known as AR Worldwide, AR now consists of a family of companies: AR RF Microwave Instrumentation, AR Modular RF, AR Receiver Systems, and AR Europe. AR’s product line includes everything from amplifiers, antennas, TWT amplifiers, complete test systems, probes, monitors, software, and receivers to amplifier modules that can be customized to the toughest specs. After four decades of growth, its founder has an understandably expansive outlook and remarks, “We’re one company with infinite solutions. And after 40 years, we’re only just beginning.”See the official announcement on the AR website.
