  • Patent number: 9570222
    Abstract: An inductor component includes a plurality of conductive elements, each formed as an individual patch of conductive material, with the conductive elements arranged in a vertical stack and tightly coupled to one another. Dielectric is disposed between more adjacent conductive elements, the dielectric has a permittivity and is sufficiently thin so as to provide a mutual inductance factor of at least one-half or greater between adjacent ones of the conductive elements. The dielectric is typically thinner than the adjacent conductors.
    Type: Grant

  • Patent number: 9324490
    Abstract: Apparatus and methods for vector inductors are provided herein. In certain configurations, an apparatus includes a vector inductor comprising a plurality of conductors arranged in a stack and separated from one another by dielectric. The conductors are tightly coupled to one another to provide a relatively high amount of mutual inductance. For example, adjacent conductors in the stack can be mutually coupled with a coupling coefficient k that is at least 0.5, or more particularly, 0.9 or greater. In certain implementations, the conductors are electrically connected in parallel with one another to provide the vector inductor with low resistance. However, tight coupling between the conductors in the stack can result in vector inductor having an overall inductance that is similar to that of a self-inductance of an individual conductor in the stack. The Q-factor of the vector inductor can be increased by the inclusion of additional conductors in the stack.

  • Publication number: 20140354370
    Abstract: A signal handler providing high linearity in a small size, applicable across wide operating frequencies and bandwidths, while also adapted to preferred integrated circuit (IC) and printed circuit board technologies. In one implementation, a signal handling apparatus includes an input impedance transformer for receiving an input signal and matching an internal apparatus impedance, a splitter for providing N split signals, a number of signal processing circuits for processing the N split signals, a combiner for combining the N split signals into a combined signal, and output impedance transformer for receiving the combined signal and for matching the internal apparatus impedance to an output impedance of the apparatus. The apparatus may provide filtering, duplexing and other radio frequency signal processing functions. A tunable duplexer may be implemented using a vector inductor and tunable capacitor array with frequency dependent impedance transformers.
