A broadband matching network design is given with its simulation and prototype measurement results. The circuit contains certain number of cascaded unit-elements (UEs) and open-stubs which behave as Richards capacitors. Richards domain driving point immittance (impedance or admittance) function of the network is obtained utilizing the Real Frequency Direct Computational Technique (RFDCT). Synthesis of the immittance function via "high precision Richards synthesis package" yields the characteristic impedances of microstrip unit-elements, open and short stubs. Kuroda transforms are used to convert short-stubs to open-stubs due to their difficulties in manufacturing. Theoretical design, simulation and measurements are in a good agreement.
