摘要： A mixer circuitry 100 comprises a mixer (110), an LO leakage detector (120), a digital LO leakage cancellation controller (130) and a DAC arrangement (140). The mixer (110) is configured to mix a first local oscillator, LO, signal having an LO frequency fLo with an intermediate frequency, IF, signal and generate an output signal, i.e. a wanted signal. The LO leakage detector (120) measures the LO leakage at the output of the mixer (110) in the presence of the wanted signal. Then in the digital LO leakage cancellation controller (130), a digital algorithm is run that automatically adjusts the LO leakage in the mixer by steering the digital-to-analog converter arrangement (140) such that the intermediate frequency input signal level to the mixer is adjusted.

摘要： Various systems and methods for disabling UAVs are presented. An interrogation system may transmit an identifier request message to a UAV. The interrogation system may receive, in response to the identifier request message, a response message that indicates a UAV identifier. The interrogation system may access one or more UAV identifier databases that relate UAV identifiers with airspace definitions. The interrogation system may retrieve from the one or more UAV identifier database systems an airspace definition corresponding to the UAV identifier. The interrogation system may determine that the UAV is to be disabled based on: a location of the UAV, a restricted airspace definition, and the airspace definition corresponding to the UAV identifier. The interrogation system may then transmit a disablement instruction message to the UAV based on the location of the UAV and the airspace definition corresponding to the UAV identifier.
