Cpw impedance match
WebWe propose a novel design concept to continuously vary the widths of the signal trace and grounds of a conventional coplanar waveguide (CPW) to achieve a predefined matching … WebA quarter-wave impedance transformer is used for impedance matching in circuits where the load impedance is real. It is particularly suitable for impedance matching in the following cases: Impedance matching between a resistive load and transmission lines. Impedance matching between two resistive loads.
