Abstract

Eine Filterschaltung umfaßt ein symmetrisches Tor (204), ein unsymmetrisches Tor (202) und ein Substrat (S). Eine Serienschaltung aus einer Filterstufe (206) und einem Symmetrierbauglied (208) ist zwischen dem symmetrischen Tor (204) und dem unsymmetrischen Tor (202) angeordnet. Das Symmetrierbauglied (208) und die Filterstufe (206) sind auf dem Substrat (S) gebildet.
