On distributed amplification

The response characteristics of a distributed amplifier are discussed. It is shown that they may be improved by making the delay characteristics of the anode line and the grid line different. This method, which may be called ¿staggering,¿ may be applied with advantage to almost all the conventional circuits employed in constructing distributed amplifiers. It enables one to obtain a flatter gain/frequency characteristic and a more linear phase-shift/frequency characteristic than could be obtained with the corresponding unstaggered amplifier. Photographic records of the response of experimental amplifiers to a step-voltage input show this improvement very clearly.
