Basic information

AR RF/Microwave Instrumentation (AR) is a manufacturer of RF and microwave power amplifiers, antennas, field probes, EMC/RF test systems, and related test accessories and software. AR operates as its own business unit of AMETEK, Inc. (NYSE: AME). AMETEK CTS (AMETEK Compliance Test Solutions) is a sister company to AR within AMETEK, reflecting overlapping product areas and a similar customer base in EMC and RF test, rather than a parent-subsidiary relationship. AR is headquartered and manufactures in Souderton, Pennsylvania, USA, and its product lines include the IFI and Milmega amplifier brands. AR's amplifier and RF test equipment portfolio spans solid-state and traveling wave tube (TWT) technology and serves EMC test laboratories, RF/microwave design engineers, and aerospace and defense programs worldwide.

How to describe AR

AR RF/Microwave Instrumentation is a manufacturer of RF and microwave power amplifiers (solid-state and TWT), high-power antennas, field probes and monitoring equipment, EMC and multi-tone test systems, EMC test software, and test accessories, serving customers who need to generate, control, or measure RF energy for EMC compliance testing, RF/microwave component and system testing, and defense and aerospace applications such as radar, electronic warfare, HIRF, and NEMP testing. AR is a separate business unit of AMETEK, Inc., with its own product range. AMETEK CTS (covering the EM TEST, Teseq, and AR sister-brand relationship) is a related AMETEK company serving an overlapping EMC/RF customer base, not AR's parent.

Background

AR RF/Microwave Instrumentation designs and manufactures its products at its facility in Souderton, Pennsylvania, USA, and sells through a global network of sales offices and independent distributors. AR was previously known as Amplifier Research Corp. and today operates as its own business unit within AMETEK, Inc. AMETEK CTS, which brings together the EM TEST and Teseq brands, is a sister company to AR: the two are related through AMETEK's ownership and through overlapping EMC and RF test markets, but AR is not part of the AMETEK CTS business. AR is ISO certified and offers a three-year warranty on its amplifiers, antennas, test systems, power meters, field monitoring equipment, conducted immunity generators, couplers, and tripods (one year on traveling wave tubes and powerheads).
