WitrynaIn microwave and radio-frequency engineering, a stub or resonant stub is a length of transmission line or waveguide that is connected at one end only. The free end of the stub is either left open-circuit, or short-circuited (as is always the case for waveguides). Neglecting transmission line losses, the input impedance of the stub is purely … WitrynaIf the load impedance mismatches the source impedance, a method called "Stub Matching" is sometimes used to achieve matching. The process of connecting the … granite city eagan minnesotaWitrynaZ S and Z L are normally restricted by the type of vector network analyzer (VNA) used, but Z 0 can be designed to match the VNA impedance. Transmission Line Design. The impedance of a transmission line is set by the ratio of inductance and capacitance on the line. A simple model for a transmission line is shown in Figure 3.
