摘要： In an exemplary embodiment, a phased array antenna comprises multiple subcircuits in communication with multiple radiating elements. The radio frequency signals are adjusted for both polarization control and beam steering. In a receive embodiment, multiple RF signals are received and combined into at least one receive beam output. In a transmit embodiment, at least one transmit beam input is divided and transmitted through multiple radiating elements. In an exemplary embodiment, the phased array antenna provides multi-beam formation over multiple operating frequency bands. The wideband nature of the active components allows for operation over multiple frequency bands simultaneously. Furthermore, the antenna polarization may be static or dynamically controlled at the subarray or radiating element level.

摘要： This disclosure may relate generally to systems, devices, and methods for a phased array illuminated reflector dish RF antenna combining a phased array with a microwave reflector dish and using beam steering to align the antenna beam to maximize antenna performance. The phased array may be connected in communication with one of a transmitter, a receiver, and a transceiver. In various exemplary embodiments the phased array illuminated reflector dish RF antenna includes a boom arm supporting the microwave reflector dish and the phased array. In one exemplary embodiment, the phased array only communicates signals with a remote source of the signals via the microwave reflector dish (not directly). The RF antenna system may be configured to be rough pointed by mechanically aiming the RF antenna system, and the RF antenna system is configured to fine tune aim the beam of said RF antenna system by beam steering.

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.

摘要： A multistage MMIC power amplifier with diagonal oriented field effect transistors (FETs) provides higher power output for a smaller MMIC die size. Corporate feed structures divide the RF input signal and combine the RF output signals and in a base two fashion. The corporate feed structures allow the FETs of the amplifier stages operate in-phase with adjacent circuitry appearing as an even-mode open circuit. The MMIC power amplifier is suitable for applications where reduced size, high efficiency and high gain are important, such as in commercial communication systems.
