More Information
Summary:A strip transmission filter has resonators (2,3) with impedance skips (2', 3') in addition to coupling structures (7,8) in a ceramic substrate. The ceramic substrate (1) has a metallic coating on all sides other than the front face (12) with coupling structures. According to the invention, the ceramic substrate (1) is graded in the area of the coupling structures (6,9) and at least one frame terminal (4-6). This improves metallic coating adhesion and facilitates soldering.
