  • Variable passive intermodulation load
    Patent number: 10942206
    Abstract: In one embodiment, the PIM load includes a variable attenuator; a detector configured to detect a signal characteristic associated with a signal received by the PIM load; and a controller configured to control the variable attenuator based on output from the detector.
    Type: Grant

  • Switching regulator power supply with constant current option
    Patent number: 9571047
    Abstract: A dual mode regulator provides power to a tower mounted low noise amplifier (LNA) and operates in either one of two modes. The dual mode regulator comprises a microcontroller that controls the amplifier and two regulators to operate in an Antenna Interface Standards Group (AISG) mode when the microcontroller is detecting AISG protocol information or in a current window alarm (CWA) mode when the microcontroller is not receiving AISG protocol information. In the CWA mode the total current to the two regulators and associated circuitry is maintained at a constant amplitude. Further in the CWA mode, the microcontroller is able to generate an alarm signal and deactivate the amplifier when it detects improper operation by the amplifier. In the AISG mode, a single regulator is used and the other regulator is de-activated by the microcontroller.
