Cryogenic high power filters for high frequency shipboard applications

摘要

Systems and methods are disclosed relating to transmission of communications via high frequency antenna systems employing high-temperature superconductor filters and/or amplifiers. In certain embodiments, a comb linear amplifier combiner may be modified with, for example, cryogenically cooled and/or high-temperature superconductor components, such as matching units of bandpass filters. A computer control unit may be coupled to the transmission circuit to control operation of one or more of the low-power transmitters, filters, and/or amplifiers.
