  • Patent number: 10109903
    Abstract: 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 are 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 provide various stub configurations of an RF filter and emulate various distributed filter elements and their configuration geometries. The deposited conductive traces also form other electronic components to be used in conjunction with the RF filter elements. A wirebond or bond via array (BVATM) version provides flipped RF and microwave filters.

  • Patent number: 9583812
    Abstract: A signal transmission line includes a signal conductor and an array of resonators. The resonators can include split resonators. The array of resonators can partially overlap with the signal conductor of the signal transmission line. In some embodiments, the portion of the signal conductor overlapping with the split ring resonators is wider than the portion of the signal conductor outside the overlapping area. The signal transmission line can be tuned for a range of frequencies. For example, the signal transmission line can be tuned to have an absolute value of a s-parameter less than or equal to 1 dB for a range of frequencies. The signal transmission line can be less than or equal to 200 microns in thickness and may also be flexible.
