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.
