摘要： Systems and method are provided for a switching circuit that enables attenuation of high power signals in relatively small band(s) without attenuating information in other bands. Embodiments of the present disclosure provide switching circuits with intrinsically switched filters that enable channelized limiting without affecting adjacent channels. Further, embodiments of the present disclosure provide a unique filter coupling topology that enables filters to be switched on or off without changing the input impedance of the filters.

摘要： A waveguide filter for the transmission of an RF signal comprising a plurality of blocks of dielectric material coupled together in a combined side-by-side and stacked relationship. Each of the blocks defines resonators and includes an exterior surface that is covered with a layer of conductive material and defines internal layers of conductive material with the blocks coupled together. The internal layers of conductive material include regions devoid of conductive material that define internal windows for the transmission of the RF signal between resonators in the side-by-side and stacked blocks. The internal layers of conductive material also include regions devoid of conductive material that define isolated pads of conductive material for the indirect transmission of the RF signal between resonators in the stacked blocks.

摘要： A switching device includes a first electrode at least partially disposed within a sealed chamber. The sealed chamber encloses a plasma phase change material. The switching device includes a second electrode at least partially disposed within the sealed chamber. The second electrode is physically separated from the first electrode. When subjected to a signal that satisfies a threshold, the plasma phase change material forms a plasma within the sealed chamber. The first electrode is electrically coupled to the second electrode via the plasma when the plasma is formed. The first electrode is electrically isolated from the second electrode when the plasma is not formed. The switching device includes a first connector electrically coupled to the first electrode and a second connector electrically coupled to the second electrode. The first connector, the second connector, or both, are configured to receive the signal.
