Stability and improved circuit modeling considerations for high power MMIC amplifiers

The cluster-matching approach for large-periphery power FETs brings with it certain problems including more complex circuitry and additional modes of possible oscillations. Solutions to these problems are offered including an analysis of the modes along with methods of suppression and improved circuit modeling. These solutions were implemented in the design of a two-stage, 1.6-W monolithic power amplifier which is also discussed.<
