Abstract :
This paper deals with the minimisation of the tunability factor. This represents the input port sensitivity of the amplifier circuit to all parametric load alterations, and acquires importance especially when the design specifications are so strict that no tolerance margin is given for placing of the input and output reflection coefficients. An operative procedure, combining graphical and numerical techniques, is also shown, which allows a simple design of the system parts
