    摘要: A multiple-path, configurable, radio-frequency (RF) circuit is provided, including: a first amplifier path amplify a first RF signal to generate a first amplified signal; a second amplifier path configured to amplify a second RF signal to generate a second amplified signal; a corrective input matching circuit, configured to change first input-impedance-matching properties of the first amplifier path, and to change second input-impedance-matching properties of the second amplifier path; a first isolation element configured to selectively ground an input node of the second amplifier path; a second isolation element configured to selectively ground an output node of the second amplifier path; and a third isolation element connected between the first and second amplifier paths, configured to selectively isolate the corrective input matching circuit from first and second input nodes of the first and second amplifier paths, respectively, or connect the corrective input matching circuit to the first and second input nodes.

    摘要: An output match circuit is coupled between the terminal of a high-frequency device and a ground terminal. The output match circuit includes an LC shunt and an LC notch serially coupled to the LC shunt, wherein the LC notch includes a resonant capacitive element in series with a resonant inductive element. The LC notch may simply include a resonant inductive element coupled directly to the ground terminal. The series inductive element may have a terminal coupled between the resonant capacitive element and the resonant inductive element.

    摘要: Method and apparatus for creating and maintaining frosted sculptures are described. In a preferred embodiment, the apparatus includes an armature, or a length of conduit freely formed into a desirable shape, having circulated therethrough, by reverse-sublimation means operatively coupled therewith, a freezing agent. The reverse-sublimation means preferably includes pump means, condensation means and metering means, and is capable of removing the sensible heat and the latent heat of fusion from water vapor surrounding the armature, thereby to promote growth, on the exposed surface of the armature, of a thick layer of rough-textured frost.
