  • Stackable RF filter for a receiver or transmitter
    Patent number: 11616279
    Abstract: A receiver or transmitter designed for a broad range of frequencies requires a pre-select filter for incoming signals or a post-select filter for outgoing signals to minimize spurious signal responses. In conventional receivers, several discrete RF filters are used and a switched filter bank is created utilizing a large amount of space. A filter bank comprising a plurality of stacked shielded filters would enable different filter technologies and topologies to be used together, as other passive and active circuits may be combined into the one surface mountable component in order to save on PCB space.
    Type: Grant

    Date of Patent: March 28, 2023
    Assignee: ThinkRF Corporation

  • Signal recognition in an on-frequency repeater
    Patent number: 7522556
    Abstract: An intelligent gain controller (IGC) for an on-frequency repeater implements a method for identifying a desired narrow band signal within a broadband RF signal. Thus, a candidate narrow band signal within the broadband signal is isolated. The isolated narrow band signal is then processed to detect repeating features of the narrow band signal. The detected repeating features are then analyzed to identify the signal type of the isolated narrow band signal. System gain of the in-frequency repeater can be controlled based on the power level of the identified narrow band signal.
