摘要:
In an exemplary embodiment, a phased array solid-state architecture has dual-polarized feeds and is manufactured, for example, on highly flexible silicon germanium (SiGe). The implementation of dual-polarized feeds facilitates the operation of phased arrays where the polarization can be statically or dynamically controlled on a subarray or element basis. In an exemplary embodiment, the sub-component control is configured to optimize a performance characteristic associated with polarization, such as phase or amplitude adjustment. An active phased array architecture may replace traditional distributed and GaAs implementations for the necessary functions required to operate electronically steerable phased array antennas. The architecture combines active versions of vector generators, power splitters, power combiners, and RF hybrids in a novel fashion to realize a fully or substantially monolithic solution for a wide range of antenna applications that can be realized with radiating elements having single-polarized or dual-polarized feeds.
