摘要： A dielectric resonator image reject mixer and method comprises an amplifier for amplifying a receive frequency (RF) signal and outputting a first combined signal comprising a RF signal, a RF noise signal, and an image noise signal. A dielectric resonator image rejector is coupled to the amplifier. The dielectric resonator image rejector receives the first combined signal but outputs only a second combined signal comprising the RF signal and the RF noise signal to a mixer coupled to the dielectric resonator image rejector. The image noise signal is rejected by either reflection or resonant transmission to a resistor-terminated microstrip line. A mixer mixes the combined RF signal and the RF noise signal from the dielectric resonator image rejector with a local oscillation frequency signal, producing an intermediate frequency output signal.

摘要： A method and apparatus for power combining or dividing handles high impedance line requirements in n-way combiners (15) and dividers (10) using phase delay networks (12, 14) to transform impedances to a lower, intermediate impedance. Each impedance transformation is accomplished using a stepped impedance or tapered impedance transmission line (26). The method and apparatus provides isolation between input or output ports (11, 22 and 24, 13) in power combining or dividing circuits using an incremental phase delay network (12) of prescribed electrical phase lengths (22, 24) to provide phase cancellation. The power divider (10) and combiner (15) can be used in power amplifiers and in communication devices.

摘要： In an exemplary embodiment, a monolithic active solution is configured to generate the fixed spatial beams of a Butler matrix operation or a Blass matrix operation. The exemplary Butler matrix comprises active RF hybrids and vector generators, and is designed for broadband performance in an ultra-compact size, which is size independent of the operating frequency. Furthermore, an exemplary Blass matrix comprises vector generators, active power combiners, and active power splitters. The Blass matrix is designed for broadband performance in an ultra-compact size, which is size independent of the operating frequency. Both the exemplary Butler matrix and exemplary Blass matrix may be configured generate steerable beams. Advantages of both the exemplary Butler matrix and exemplary Blass matrix include that they have neutral or slight positive power gain rather than high losses, and have ultra broadband range which enables operation over multiple frequency bands.

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： An exemplary embodiment of the feed forward amplifier replaces traditional distributed directional couplers, splitters, and delay lines. Moreover, an exemplary feed forward amplifier architecture combines active implementations of RF couplers, power splitters, and/or time delay elements in a novel fashion allowing for ultra-compact size and broadband performance.

The at least one active vector generator is configured to adjust the phase and amplitude of an error amplifier path signal and an error amplifier is configured to receive the adjusted error amplifier path signal. Furthermore, the adjusted error amplifier path signal and an amplified signal are combined to form the output signal of the feed forward amplifier.
