Abstract
A distributed amplifier is provided that includes an input network that simulates an input signal transmission line, and having an output network that simulates an output signal transmission line, and also having multiple unit cells with amplifying characteristics that are connected in parallel to one another between the input network and the output network, that amplify a signal propagating through the input network and feed it into the output network with a predetermined phase relationship to a signal propagating through the output network. The distributed amplifier is characterized in that each unit cell has a multiplier with an input amplifier and an output amplifier, a control connection of the input amplifier is connected to the input network, a current connection of the input amplifier is connected to a control connection of the output amplifier and is connected through a diode to a current connection of the output amplifier, and current outputs of the input amplifier and of the output amplifier are connected to one another.
