Graphic design of matching and interstage lossy networks for microwave transistor amplifier
Abstract
A graphical design method for lossless and lossy gain-compensating networks is presented, and the advantages of the use of this technique in the construction of microwave-transistor amplifiers are discussed. The method is based on the use of a set of constant circles plotted on the Smith Chart, and is easily automated on a personal computer. Two applications are presented: a two-stage amplifier with 20 dB in the 100-1100 MHz band and an ultra-broadband lossy matched amplifier stage with 4 dB in the dc-16 GHz band.
