Microstrip Coupled Line Filters with Spurious Band Suppression

摘要：

Passband microstrip coupled line filters are widely used in daily microwave engineering practice. These filters present an undesired pass band at twice the design central frequency of the filter. Two simple methods to suppress this drawback are reported in this communication. The proposed methods, apart from removing the spurious band, provide an extra coupling mechanism that relaxes tolerances of strip width and spacing in those cases where tightly coupled sections are required.
