Abstract:
A coaxial filter-capacitor for high frequency ranges, comprising:a signal conductor; a signal electrode connected to said signal conductor and subdivided into at least two conductor regions being separated in a direction of signal propagation and being mutually insulated from one another and each having an area; a ground conductor; a ground electrode connected to said ground conductor; a first dielectric layer having a relative dielectric constant of at least 103 disposed between said conductive regions of said signal electrode and said ground electrode; a plurality of signal connectors electrically connecting said conductor regions of said signal electrode to said signal conductor, and each signal connector respectively contacting one of said conductor regions and having a substantially smaller area than the area of the respective connected conductor region; and a second dielectric layer having a relative dielectric constant of at least 100; said signal conductor being separated from said conductive regions of said signal electrode by said second dielectric layer and thus from said first dielectric layer; and each of said signal connectors being lead through said second dielectric layer and having a relative dielectric constant of about 100.
