USING FEEDBACK TECHNIQUES TO DESIGN A STABLE AND MATCHING CONDITION FOR MICROWAVE TRANSISTOR-AMPLIFIERS

A new method is presented that is useful for the design of microwave f eedback amplifiers, including considerations on parameter representati on, normalizing impedance, stability and matching conditions. Analytic al expressions for the feedback quantity with specified terminations a re derived. This method provides insight into the effects of the feedb ack and controls the two-port parameters of the transistor amplifier f or practical applications. An example is given to illustrate this proc edure for achieving the optimum performance for stability and matching .
