The Effects of Grid Loading on the Gain and Phase-Shift Characteristics of a Distributed Amplifier

The effects of grid loading on the gain and phase-shift characteristics of staggered distributed amplifiers using constant-kandm-derived constant-kLClow-pass filter sections are discussed. It is shown that if the attenuation in the grid line due to grid loading is substantial, the staggering of the lines in general will not much improve the gain characteristics of the amplifier.
