#Yz smith chart full
Uses the full graphics capabilities of the Windows ® operating system for network entry, analysis controls and displayed results. Based on the venerable and highly intuitive Smith chart, it provides high-accuracy computations without recourse to paper, compass or straightedge. This graphics-intensive program is a valuable transmission-line calculator for both advanced and beginning users. Provided the frequencies are sufficiently close, the resulting Smith chart points may be joined by straight lines to create a locus. This is often adequate for narrow band applications (typically up to about 5% to 10% bandwidth) but for wider bandwidths it is usually necessary to apply Smith chart techniques at more than one frequency across the operating frequency band. Use of the Smith chart and the interpretation of the results obtained using it requires a good understanding of AC circuit theory and transmission line theory, both of which are pre-requisites for RF engineers.Īs impedances and admittances change with frequency, problems using the Smith chart can only be solved manually using one frequency at a time, the result being represented by a point. The Smith chart may also be used for lumped element matching and analysis problems. The degrees scale represents the angle of the voltage reflection coefficient at that point.
#Yz smith chart generator
The wavelengths scale is used in distributed component problems and represents the distance measured along the transmission line connected between the generator or source and the load to the point under consideration. The Smith chart has circumferential scaling in wavelengths and degrees.
With relatively simple graphical construction it is straighforward to convert between normalised impedance (or normalised admittance) and the corresponding complex voltage reflection coefficient. Normalised scaling allows the Smith chart to be used for problems involving any characteristic impedance or system impedance, although by far the most commonly used is 50 ohms. These are often known as the Z, Y and YZ Smith charts respectively. The Smith chart is plotted on the complex reflection coefficient plane in two dimensions and is scaled in normalised impedance (the most common), normalised admittance or both, using different colours to distinguish between them.
