    摘要： Systems, devices, and methods are provided for actively biasing a multi-stage amplifier. A method for differentially actively biasing a multi-stage amplifier comprises the steps of: actively biasing, with a single active bias circuit, an amplifier comprising a plurality of amplification stages; and differentially applying the bias provided by the single active bias circuit by biasing at least one amplification stage at a different bias level than another of the plurality of amplification stages. An active bias circuit for a multi-stage amplifier comprises: a single active bias circuit that is configured to actively bias a plurality of amplification stages via at least two gates; and a differential device configured to cause the active biasing provided to one gate to be different from the bias provided to another gate.

    摘要： In general, in accordance with an exemplary aspect of the present invention, a low-loss interface for connecting an integrated circuit such as a monolithic microwave integrated circuit to an energy transmission device such as a waveguide is disclosed. The interface comprises an isolation wall placed between an input and output region of an integrated circuit to reduce ripple and isolate the waveguide cavity from the monolithic microwave integrated circuit circuitry. The interface further comprises a turning screw or other similar member that is configured to closely match the impedance of integrated circuit 11 with the impedance at interface 10 to further reduce loss.

    摘要： A device for infusing flavor into liquids fits and seals to the neck of a bottle. The device has an infusing chamber that is selectively in fluid communication with the liquid in the bottle. The infusing chamber holds a replaceable infusing material that partially dissolves and infuses flavor as liquid passes over it. A check ball selectively separates the infusing chamber from the liquid in the bottle to prevent any infused liquid from returning to the bottle. The device has a passage for makeup air to enter the bottle as infused liquid is dispensed. The infusing material is replaceable by accessing the infusing chamber.
