A series of CAD techniques for designing microwave feedback amplifiers and simplifying the design of reactively matched single-ended amplifiers

A series of CAD techniques is introduced which is useful for modifying the characteristics of transistors for use in microwave amplifiers. Two applications are presented: in the first, some of these techniques are applied to the design of feedback amplifiers, and in the second, two transistors are modified for easier matching and a flat transducer power gain versus frequency response in a single-stage amplifier configuration. The results obtainable with some of these techniques are illustrated with examples showing their usefulness.<>
