High-power terminations incorporate forced-air cooling

They are available in a variety of different waveguide sizes to suit operating frequencies ranging from 1.12GHz to 40GHz and are equipped with an AC- or DC-input fan, together with an external cowling to direct the airflow over the cooling fins.
Designed and manufactured at Link Microtek’s premises in the centre of Basingstoke, the terminations are fabricated as standard from light-weight Alochromed aluminium with a black satin paint finish. Internal elements are made from highly absorbent cast ceramic material, rated at up to 3000degC.
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.
