  • Patent number: 9929707
    Abstract: An embodiment of a distributed amplifier includes an output collection line, a plurality of tap nodes distributed along the output collection line, and a plurality of amplification paths coupled to the tap nodes. An embodiment of an amplification path includes an amplifier and a compensation circuit. The amplifier is configured to receive and amplify an input RF signal to produce an amplified RF signal at an amplifier output. A compensation circuit input is electrically coupled to the amplifier output, and a compensation circuit output is electrically coupled to one of the tap nodes. The compensation circuit includes a series inductance electrically coupled between the compensation circuit input and the compensation circuit output, and a shunt capacitance electrically coupled between the series inductance and a ground reference node. The amplifiers and the compensation circuit may be monolithically implemented on a single substrate, or may be implemented on separate substrates.
