  • Distributed amplifier for band pass radio front-end
    Patent number: 8686790
    Abstract: A distributed amplifier is provided that is broadband and band pass with controllable bandwidth. In the distributed amplifier circuit, termination impedance of the input transmission line is not matched with the characteristics impedance of the input transmission line and/or the termination impedance of the output transmission line is not matched with the characteristics impedance of the output transmission line, thus providing the broadband and band pass with controllable bandwidth attributes.
    Type: Grant
