An Innovative Approach for Microwave Circuit Design and Analysis Using Fully Symmetrical Planar Smith Chart

This paper discusses the graphical procedures for designing and analyzing any active and/or passive microwave circuit using a fully symmetrical planar Smith Chart based on Mercator projection. To illustrate it with the examples, an equivalent circuit of tunnel diode having a negative resistance is considered. The second example elaborates on the design of an L-section impedance matching circuit. These graphical procedures can be used to design and analyze, hence, to calculate the equivalent impedance and/or admittance of any microwave active/passive circuit consisting of lumped and/or distributed elements.
