    摘要: A system and method for operating a system including at least one active electronically scanned array (AESA) element incorporates drain voltage amplifier control (DRAVAC) to maintain the power amplifiers of the AESA elements at a constant gain compression level. A processor of the AESA system may dynamically program, monitor, or adjust each individual array element or component thereof. As the RF output power of the power amplifiers varies, constant gain compression is achieved by dynamically adjusting the RF input power and drain voltage to the power amplifiers. An AESA element may incorporate built-in self-test circuitry for detecting faults in the power supply to the power amplifiers as well as calibrating and calculating RF output power for a given input power by controlling the bias of a pass device serving as the amplifier current source.

    摘要: The present disclosure is directed to optically-tuned electronic components including one or more layers of photosensitive semiconductive materials. In some embodiments, an optically-tuned electronic component includes a plurality of device layers have different bandgap characteristics. One or more selected layers can be optically activated (i.e. made substantially conductive) by illuminating at least a portion of each selected layer with illumination having a wavelength shorter than or substantially equal to the activation wavelength of each selected layer. Accordingly, various parameters can be tuned or a circuit can be switched between alternative paths by providing one or more selected wavelengths of illumination.
