Abstract
A high frequency, stripline filter may have a bottom surface for mounting to a mounting surface. The filter may include a monolithic base substrate having a top surface and a plurality of thin-film microstrips, including a first thin-film microstrip and a second thin-film microstrip, formed over the top surface of the substrate. Each of the plurality of thin-film microstrips may have a first arm, a second arm parallel to the first arm, and a base portion connected with the first and second arms. A port may be exposed along the bottom surface of the filter. A conductive path may include a via formed in the substrate. The conductive path may electrically connect the first thin-film microstrip with the port on the bottom surface of the filter. The filter may exhibit an insertion loss that is greater than −3.5 dB at a frequency that is greater than about 15 GHz.
