Abstract
A suitable large signal design method of distributed power amplifiers, based on the optimum FET load requirement for high power operation, i s proposed in this article, The gate and drain line characteristic adm ittances are determined, providing both the initial values and right d irections for an optimum design, To validate the proposed design metho d, a FET amplifier demonstrator with a gate periphery of 1.2 mm has be en manufactured at the Texas Instruments foundry, The MMIC distributed amplifier demonstrated an improved power density performance of 340 m W/mm over the 2-18-GHz frequency band associated with a minimum of 13% power-added efficiency and 24% drain efficiency at 1-dB compression i n CW operation.
