  • RF integrated circuit with tunable component and memory
    Patent number: 9960791
    Abstract: An RFIC with memory is described where the memory can be used to house a look-up table for tuning components designed into the RFIC, providing a customized tuning circuit for antenna and transceiver front-end tuning applications. The look-up table can be loaded at wafer level during the manufacturing process to customize an RFIC design for a specific antenna system. The memory can be used to restrict or tailor the tuning range of tunable capacitors and switches within the RFIC to optimize performance in the end application.

  • MODAL ADAPTIVE ANTENNA USING REFERENCE SIGNAL LTE PROTOCOL
    Publication number: 20180040952
    Abstract: One or more input signals are used to generate a Pseudo noise generator and re-inject the signal to obtain a more efficient method of control of a receiver using adaptive antenna array technology. The antenna array automatically adjusts its direction to the optimum using information obtained from the input signal by the receiving antenna elements. The input signals may be stored in memory for retrieval, comparison and then used to optimize reception. The difference between the outputs of the memorized signals and the reference signal is used as an error signal. One or multiple Modal antennas, where the Modal antenna is capable of generating several unique radiation patterns, can implement this optimization technique in a MIMO configuration.
