High Power / HiRF EMC Test Systems
Q-par Angus Ltd. have teamed up with TMD Technologies Ltd. to produce a set of antenna and amplifier solutions that provide unrivalled field strengths in EMC tests, exceeding the latest aerospace requirements.
The horn antennas have been specially developed by Q-par Angus to deliberately focus the RF energy at short distances from the aperture, and thus overcome the near field limitations of traditional designs.
Various mounting options are available for these antennas, depending on your budget or test requirements, ranging from a fixed mount to fully variable geometry. The Mounting Systems brochure shows the most sophisticated version. This is based on a common mobile mounting frame serving the entire antenna range and has variable height, inclination and polarisation controls. All our mounting options are designed to make adjustments as quick and easy as possible with the minimum of downtime.
Focussing is achieved either by using dielectric lenses or by dividing the aperture up into four cophased smaller horn antennas. In the latter case the horns are also squinted in towards the target. The squint angle is adjustable: this allows the spot size to be traded off against field intensity to suit test conditions.
Features
- Nine specialised antennas cover the frequency range 0.4 - 18 GHz.
- Six broadband amplifiers cover the range 1 to 18 GHz, each having output powers in excess of 4 kW.
- In excess of 3 kV / m at one metre is now achievable in free field tests.
- 3 dB spot sizes are 150 mm or greater.
- All exceed Latest Category K specification.
