Abstract: A phased array antenna which can change the configuration of the phased array antenna by controllable quad switches on the phased array antenna is presented. The phased array antenna adapts monolithic microwave integrate circuit (MMIC) technology to have high isolation interconnection of the reconfigurable phased array antenna. The reconfigurable phased array antenna can be reusable and adaptable to different configurations so that the overall cost and lead time of the phased array antenna is reduced compared to the existing RF antennas in the market.

Abstract: An amplifier for amplifying signals is presented. A cascode power amplifies includes two or more adjacent cascode amplifiers and at least one remote cascode amplifier. The adjacent cascode amplifiers are lined up adjacent each other with inputs of the adjacent cascode amplifiers connected to a common input line and outputs of the of adjacent cascode amplifiers connected to a common output line. The adjacent cascode amplifiers generally operate in parallel. The remote cascode amplifier is spaced apart from the adjacent cascade amplifiers. An input transmission line connects an input of the remote cascode amplifier to the common input line. An output transmission line connects an output of the remote cascode amplifier to the common output line. Amplified outputs of the adjacent cascode amplifiers and amplified outputs of the remote cascode amplifier are power combined and summed into a coherent amplified output signal that is output on the output transmission line.

Abstract: A system and method for amplifying and wave shaping a signal is presented. A system includes a Class F/Inverse Class F radio frequency (RF) power amplifier (PA). The RF PA includes an amplifier and an output matching network. The amplifier amplifies a radio wave signal to produce and an amplified signal. The output matching network wave shapes the amplified signal using a plurality of tuning stubs to generate an output signal. The tuning stubs operate at different harmonics of the amplified signal. When operating in a Class F mode the plurality of tuning stubs act as short circuits at even harmonics and the plurality of tuning stubs act as open circuits at odd harmonics. When operating in an Inverse Class F mode the plurality of tuning stubs act as open circuits and at even harmonics the plurality of tuning stubs act as short circuits at odd harmonics.
