Using Calibration to Optimize Performance in Crucial Measurements
Amplifier Research (AR RF/Microwave Instrumentation) began in 1969 with just two men in a cellar, moonlighting from their regular jobs. Don (“Shep”) Shepherd and his late partner, Dan Roth, worked for AEL (American Electronics Laboratories), producing radio frequency designs for military applications. They saw a market for their skills in designing amplifiers for test applications, but AEL was not set up for such jobs. So they decided to try and make it on their own, working out of a makeshift laboratory in Shep’s cellar. The first sale was a 2 watt, 250 MHz amplifier that sold for $600 including $60 for special connectors.
In 1973, AR moved its headquarters to Souderton, PA and 3 years later introduced a 10,000 watt, 10 kHz–100 MHz tube amplifier that’s still available today. AR expanded its capabilities in 2001 with the acquisition of Kalmus in Bothell, WA to include amplifier modules and amplifier systems. A year later, Carnel Labs in Canoga Park CA joined the AR family.
Today, AR, celebrating 40 years in business in 2009, has grown dramatically from the 2-person company that started in Shep’s cellar to a corporation that employs over 200 people and continues to lead the industry with innovative, superior quality, technologically-advanced products and a global support system that’s second to none.
