Rectangular-waveguide terminations enable testing and maintenance of radar systems
Link Microtek
AM-L4 ’dummy’ loads
Link Microtek’s Engineering Division has introduced a range of rectangular-waveguide terminations for the testing and maintenance of radar systems and other high-power microwave equipment.
The AM-L4 ’dummy’ loads incorporate forced-air cooling as standard, enabling them to offer a higher power-handling capability than convection-cooled alternatives, according to the company.
They are designed to safely absorb microwave signals with a mean power in excess of 1kW.
Available options for the AM-L4 terminations include temperature sensors to provide protection against overheating and power samplers to allow monitoring of microwave power levels.
Key specifications
- Available in a variety of waveguide sizes to suit operating frequencies ranging from 1.12GHz to 40GHz
- Equipped with an AC- or DC-input fan, together with an external cowling to direct the airflow over the cooling fins
- Fabricated as standard from lightweight Alochromed aluminium with a black satin paint finish
- Internal elements made from highly absorbent cast-ceramic material, rated at up to 3,000C
