AR - RF/Microwave Instrumentation have introduced a suite of three high-gain, high-power microwave horn antennas for use in DO 160 HIRF (High Intensity Radiated Frequency) testing. These microwave horn antennas are available from Faraday .

AR - RF/Microwave Instrumentation amplifiers and antennas are critical components in DO 160 HIRF testing due to their ability to generate high intensity field strengths. 

The new antennas for DO 160 HIRF testing include:

  • AT4444 – 2 to 4 GHz / 1000 watts CW / 17 kw pulse input power
  • AT4446 – 4 to 6 GHz / 800 watts CW / 15 kw pulse input power
  • AT4448 – 6 to 8 GHz / 700 Watts CW (6-7.5 GHz), 600 Watts CW (7.5-8GHz) /10kW pulse input power

These are all high-gain, high-power microwave horn antennas that provide a minimum of 18 dB over isotropic. These antennas supply high intensity fields for DO 160 HIRF testing and are compact and lightweight for easy mobility.

The microwave horn antennas are tough to withstand the demands of outdoor use. All three antennas are designed to mount easily on a tripod or to a mounting plate and can be used with AR - RF/Microwave Instrumentation power-pulsed travelling wave tube amplifiers.

HIRF testing is important due to the high electromagnetic fields caused from friendly radars and other electronic devices, or generated by enemy/terrorist forces, which are a real danger to electronic equipment. These high EM fields can detonate electronically-controlled explosive devices or disable an aircraft’s avionics.
