Abstract

A zero-IF-converter, particularly for digital satellite receivers, comprising a thin-film component including at least two RC filters each including a resistor and a capacitor which each comprise a lower electrode, an upper electrode and a dielectric material, said RC filters being arranged on a common substrate, is characterized by a constant amplitude and phase relationship between the base band signals I and Q.
