RFC is an impedance calculator dedicated to Radio Frequency design engineers and students Using the program you can synthetize and analyze an electric matching network composed of impedances, inductors, capacitors, transmission lines and ideal transformers The goal of the program is to match impedances; the number of elements of the electric network must be less than nine Each element of the network has one or two variable parameters. You can tune the parameters by keyboard and the resulting graph is dynamically updated on the screen The screen shows the coefficient of reflection plane in its complex form Bilinear transformations of the coefficient of reflection plane, the well known Smith (R) Charts can be superimposed for presentation purposes and design aid The program uses exact formulas obtained from Maxwell equations and circuit theory The graph associated to each element is obtained by sweeping a parameter from zero to its nominal value The RFC keyboard is "a sea of trimmers" enabling fast optimizations by a highly interactive user interface
