High-power microwave terminations

25 January 2012 Telecoms, Datacoms, Wireless, IoT

Link Microtek has introduced a range of rectangular waveguide terminations that incorporate forced air cooling as standard, enabling them to offer a higher Power handling capability than convection cooled alternatives.

Ideal for the testing and maintenance of radar systems and other high-power microwave equipment, the AM-L4 ‘dummy’ loads are designed to safely absorb microwave signals with a mean power in excess of 1 kW. They are available in a variety of different waveguide sizes to suit operating frequencies ranging from 1,12 GHz to 40 GHz and are equipped with an AC- or DC-input fan, together with an external cowling to direct the airflow over the cooling fins.

The terminations are fabricated as standard from lightweight Alochromed aluminium with a black satin paint finish. Internal elements are made from highly absorbent cast ceramic material, rated at up to 3000°C. Available options include temperature sensors to provide protection against overheating and power samplers to allow monitoring of microwave power levels.
