The invention relates to a high-pass branch () of a frequency separating filter for ADSL systems comprising inductive components () which dispose of magnet cores made of a soft magnetic amorphous or nanocrystalline. As a result, frequency separating filters are provided which comprise small structural shapes and which have especially beneficial properties in the relevant frequency and temperature range.

High-pass branch of a frequency separating filter for ADSL systems

A filter system includes at least two longitudinal branches with longitudinal inductors and at least one filter section (B) and an adjacent filter section (A). The filter section (B) is provided with at least one transverse branch that is interposed between the longitudinal branches, the adjacent filter section (A) adjoining the transverse branch. The number of inductors of a filter section that arc wound around different magnet cores can be reduced by equivalence transformation.

Method for designing a filter system

Low-pass filter for a diplexer in an ADSL communications system comprising a low-pass filter ( ) with chokes ( ). Said chokes ( ) have magnetic cores made of an alloy, especially a nanocristalline or amorphous alloy.
