A New Real Frequency Line Segment Technique to Assess the Gain Bandwidth Limitations for the Double Matching Problems

In this paper, we introduced a new real frequency line segment technique (RF-LST) to assess the gain bandwidth limitation of double matching problems. The new method possesses all the outstanding features of the classical RF-LST, and it is the only practical tool available in the current literature to assess the gain-bandwidth limitations of double matching problems numerically. An example is presented to show the application of the newly proposed method. It is expected that the newly proposed RF-LST technique will be useful to assess the power and efficiency performance of interstage matching networks in designing single or multistage microwave amplifiers and communication systems such as transmitters, receivers phase array antenna systems, Electronic Warfare systems etc.
