  • CREATING UNIQUE IDENTIFICATION FOR AN ARRAY ELEMENT
    Publication number: 20140022834
    Abstract: A circuit arrangement for assigning identification address to each element of an array of elements of a phased array, or assigning a unique digital word to a isolated circuit. In one embodiment two external resistors are used to provide an analog voltage. That voltage can be converted to digital word and stored in a chip using latches and registers. The stored digital word can then be use as address for the army element used in phased array. Thereby access to the array element can achieved using the address as a header of a digital bit stream.

  • Spur mitigation in a heterodyne upconversion system
    Patent number: 11082079
    Abstract: Exemplary embodiments dynamically select the LO frequency and mixer mode (i.e., low-side LO injection or high-side LO injection) for upconversion based on the desired RF output frequency in order to mitigate the effects of spurious and LO leakage signals that could violate radiation emission limits, e.g., in the case where the IF signal frequency is smaller than the RF operating band. By dynamically switching the LO frequency and mixer mode as a function of the requested operating RF channel, low-level emissions and spurious signal compliance with restricted bands can be achieved.
