    Abstract: An amplifier for amplifying signals is presented. A cascode power amplifier 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 cascode 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 for power amplification is presented. A tile array power amplifier (PA) module for use in a phased array includes a module with a radio frequency (RF) side and a direct current (DC) side, a top edge, a left edge a bottom edge and a right edge. Four PA dies are mounted in each quadrature of the RF side of the module. RF input connectors are mounted on the RF side to bring RF inputs to the PA dies. RF output connectors are mounted to the DC side to output amplified signals from the PA dies. The PA dies are formed, in part, with gallium nitride (GaN) and are mounted to the module in such a way that the tile array PA module is able to generate about 100 watts of RF power and dissipate about 200 watts of heat while amplifying signals over 10 GHz.

    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.
