Abstract (en)
[origin: US4456894A] Conventional attenuators and matched loads for dissipating power at hyperfrequencies are uniform structures giving constant attenuation per unit length. This results in most power being dissipated at an input end. The present invention increases the maximum total power that such a resistance can dissipate by providing a non-uniform structure in which dissipation per unit length increases when going away from an input end, in such a manner that power is dissipated in a substantially uniform manner throughout the structure. A series resistance (3) between two parallel resistances (4 and 5) are in the shape of a sector of a circle.
Abstract (fr)
Les résistances en couches résistives série R1 et parallèle R2 en forme de secteurs de cercle (3, 4, 5) sont telles que le coefficient d'atténuation R1/R2 est progressivement croissant à partir de l'entrée (E) de façon à créer une dissipation uniforme. Applications: Atténuateurs et charges en hyperfréquence.
