  • Switchable capacitor array and method for driving a switchable capacitor array
    Patent number: 10033353
    Abstract: An improved switchable capacitor array comprises a plurality of n?2 capacitor units, each comprising a capacitor with a capacitance and a switch unit. The capacitor units are electrically connected in series. Equidistantly spaced impedance values can be obtained if the values of the capacitances are chosen properly.

  • RF device and method for tuning an RF device
    Patent number: 9300270
    Abstract: An RF device includes a substrate and a series circuit of a tunable RF component and a DC blocking capacitor. The series circuit is arranged on the substrate and couples an RF signal terminal to a fixed voltage terminal that is electrically isolated from the RF signal terminal. The tunable RF component is coupled to the RF signal terminal, the DC blocking capacitor is coupled to the fixed voltage terminal and a driver terminal is coupled to the tunable RF component.

  • Adaptive antenna module
    Patent number: 9225065
    Abstract: A cheaper to produce, smaller and easy to drive adaptive antenna module is presented. The module comprises a signal path, an antenna, and a tuning circuit with two variable impedance elements. The tuning circuit operates over a restricted range of impedances and maintains the series resonance characteristic of the antenna.

  • Dynamic impedance matching network and method for matching an impedance between a source and a load
    Patent number: 8542078
    Abstract: An impedance matching network includes an impedance matching circuit for dynamically matching an impedance between a source and a load. Matching is done by varying the real part and the imaginary part of the impedance of the impedance matching circuit independently.

  • MEMS capacitor circuit and method
    Patent number: 8233856
    Abstract: A communications circuit processes a signal in at least one predetermined communications standard such as GSM or UMTS. A switched capacitor impedance matching unit is provided, controlled by driver control unit. The driver control unit is arranged to control the driver to start switching of the capacitors of the switched capacitor array during transition periods in the signals.
