Abstract
An attenuator for use in filtering high-frequency waves propagated in a transmission line, comprising ferrite beads having a conductor passed therethrough which are enclosed firmly within a mixture having powder of ferrimagnetic material dispersed in an organic high polymer.
Claims7
An attenuator for high-frequency waves, comprising:
- a plurality of adjacent rows of ferrite beads, said rows being in mutual juxtaposition and generally coplanar,
- the beads of each row each having a hole therethrough, with the holes in longitudinal alignment;
- a conductor extending through all of said holes and passing successively through said rows between an input and an output terminal;
- and
- a mixture of powdered ferrimagnetic material dispersed in an organic high polymer binder surrounding said ferrite beads and conductor and forming a plate in which said beads and conductor are embedded.
