The Linvill Method of High Frequency Transistor Amplifier Design
David Rubin · Defense Technical Information Center (DTIC) · 1969
The report discusses a method -- known as the Linvill method -- for determining the terminations that a transistor amplifier should have for a specified value of power gain and bandwidth. Basically, the Linvill method makes use of measured transistor parameters to develop charts from which one can read power gain and input impedance or admittance as functions of the load termination. The report gives a complete geometrical derivation of the Linvill 'stability factor,' whose value is an indication of the stability of the amplifier under various load conditions. In addition, procedure steps are given for using the charts developed for determining input and load admittances.
