High Power RF Test Sources

High Power Microwave Test Source

A modular VHF test source has been developed by MBDA UK Ltd in order to address EMC requirements for both military and non-military RF susceptibility and effects testing. This high power microwave test source comprises four subsystems: a Remote Control Unit (RCU), a Power and Control Unit (PCU), a Support Unit (SU), and a Radiating Unit (RU). The system is capable of operating from single shot up to high PRFs in either burst or continuous mode, and runs from a 24VDC power supply.

  • Operating frequency: 80MHz to 200MHz
  • 1 million pulse lifetime
  • Field levels representative of DEW sources in the far field
  • Variable Pulse repetition frequency:
  • Standard up to 20Hz continuous
  • Available with greater than 1kHz in bursts
  • High reliability: no regular maintenance required
  • Built in Safety Monitoring system

The high power microwave test source development programme has resulted in a very significant improvement to the longevity of the RF test source. A number of issues have been resolved by the use of novel techniques. These include new high voltage insulation techniques, new approaches to high voltage switch design and the reduction of high electric field stresses through the use of novel materials.
