Patent ID: 7804362

Claim:
A distributed amplifier comprising: an input transmission line for receiving on a first end an input signal; an output transmission line for outputting on a first end an output signal; an output line termination impedance coupled to a second end of the output transmission line opposite the first end of the output transmission line; a feedback impedance directly coupling from the first end of the output transmission line to a second end of the input transmission line spaced from the first end of the input transmission line, the feedback impedance arranged to negatively feed back a signal on the output transmission line to the second end of the input transmission line; and a plurality of amplifier stages each including an active device having a control terminal and two current-carrying terminals, with the control terminal coupled to the input transmission line at an intermediate position between the first and second ends of the input transmission line, and one current-carrying terminal coupled to the output transmission line at an intermediate position between the first and second ends of the output transmission line.
