VARIABLE 'CUT-OFF' ATTENUATOR FOR RECTANGULAR WAVE-GUIDES

摘要

The attenuator includes two variable-section components (13, 15) for the passage, in conditions of perfect adaptation, from a first wave-guide in the P band to a second wave-guide in the X band and vice versa. An air-filled zone (5V), the length of which can be varied in function of the desired attenuation, is situated between the two variable-section components.
