Abstract :
In this paper, new insights into the large-signal operation of distributed amplifiers are presented, using a nonlinear circuit simulation. By examining current and voltage waveforms within the amplifier it is possible to assess the interaction between the active devices, and how this affects overall performance. Results from the simulation are compared with experimental data from an MMIC amplifier to illustrate how the output power and power added efficiency can be improved.
