Amplifier Research

Amplifier Research (AR) is a manufacturer of broadband RF power amplifiers and related test accessories primarily serving the electromagnetic compatibility (EMC) testing, electronic warfare, and communications research markets. Founded in the 1960s, AR produces solid-state and traveling wave tube (TWT) amplifiers covering frequency ranges from below 1 kHz to over 40 GHz, with output power levels from milliwatts to kilowatts.

AR amplifiers are widely specified in EMC test standards for conducted and radiated immunity testing. Their product lineup includes self-contained amplifier units as well as modular systems, field probes, antennas, and complete EMC test cell solutions. The company also manufactures high-power CW and pulsed amplifiers used in radar simulation, antenna measurement, and satellite communications ground systems.

Key Product Lines

• Solid-state RF amplifiers — broadband amplifiers from 1 MHz to 18 GHz for EMC immunity and antenna testing
• TWT amplifiers — traveling wave tube amplifiers for high-power applications above 1 GHz
• EMC test systems — complete turnkey test cell configurations with amplifiers, antennas, and field probes
• Field probes and antennas — isotropic field probes and log-periodic antennas for EMC site measurements

Industries Served

Amplifier Research equipment is used in EMC compliance laboratories for IEC 61000, MIL-STD-461, and DO-160 radiated immunity testing, in aerospace and defense for electronic warfare simulation and radar testing, in telecommunications for antenna gain measurement and wireless device testing, and in government and university research facilities for RF propagation studies and high-power RF experiments.
