Amplifier Research

Founded in 1969, AR RF/Microwave Instrumentation is a world-class source for broadband high power, solid state, RF amplifiers and microwave amplifiers, TWT amplifiers, log periodic antennas and high-gain horn antennas, plus EMC test equipment, software and field probes and monitors.  AR RF/Microwave is a member of the AR family of companies that includes AR Modular RF, SunAR RF Motion and AR Europe; they are recognized around the globe for products that deliver both outstanding quality and exceptional value.

Throughout its 50 years (and counting), AR has been responsible for a number of “firsts” which have transformed not only EMC and RF testing but also the industries and equipment affected by these tests. A sampling of these innovations includes:

  • 10,000-watt tube amplifiers
  • 100-watt solid-state 100-1000 MHz instantaneous bandwidth Class A amplifier
  • First production 16,000-watt solid-state linear amplifier from 10 kHz to 225 MHz
  • 50,000-watt Class A power amplifier up to 225 MHz
  • 0.7 to 6 GHz high-power Class A & AB amplifier

Additionally, they push the limits of state-of-the-art design and have ruggedized their products to make them virtually indestructible. AR amplifiers are fully tested to the extreme to ensure customers receive a product that is built to last.
