摘要： Flipped radio frequency (RF) and microwave filters and components for compact package assemblies are provided. An example RF filter is constructed by depositing a conductive trace, such as a redistribution layer, onto a flat surface of a substrate, to form an RF filter element. The substrate is vertically mounted on a motherboard, thereby saving dedicated area. Multiple layers of substrate can be laminated into a stack and mounted so that the RF filter elements of each layer are in vertical planes with respect to a horizontal motherboard, providing dramatic reduction in size. Deposited conductive traces of an example flipped RF filter stack can provide various stub configurations of an RF filter and emulate various distributed filter elements and their configuration geometries. The deposited conductive traces can also form other electronic components to be used in conjunction with the RF filter elements. A wirebond or bond via array (BVA™) version can provide flipped RF and microwave filters.
