Abstract (en)
[origin: FR2849719A1] The Hyper frequency filter has a coaxial structure with an external conductive armature (1,1',1'') and an inner conductive armature (2,2',2'') extending axially. The armatures define a series of concentric plates (3A-3D) along an axial direction and defining successive sections of a low impedance line characteristic and a high impedance line characteristic. The concentric plates are formed in a block of foam plastic. Claims include a method of fabrication of the claimed filter.
