Note that the impedance grid is composed of constant resistance circles and constant reactance arcs. Let the loss of the second series line be zero. The VSWR at this point is 1. Navigating in the program First, a few notes about the screen snapshot.

The power of the Smith chart is the ability to present complex data visually, making possible informed judgments regarding transmission line systems, measured data, antennas, matching and other networks.

winsmity Here, the shorted transmission line stub shown in Figure 10 has been short- ened to The loss that is entered for the series trans- mission line will be the total loss in the line — not loss per hundred feet as specified in transmis- sion line charts, etc.

Instead of using a single load impedance resistive and reactive com- ponent for all frequencies, a separate load impedance can be specified for each frequency to be plotted.

As shown on the screen, the sweep range is from 15 MHz to MHz with only one sample point at this time.

It is certainly the case that some low frequency antennas use matching circuits, winsmit they don't have a choice. The name field is required.

This is typically done when designing the input and output matching circuits for smth high frequency transistor. Your request to send this item has been completed. Note that the input impedance of all three plots lies within the 1. As shown, all of these plots fall well within the 1. This is quite im- practical in real- ity.

You cannot place a 2.

A pad calculator, units converter, and free-space path loss calculator are built into the program, because it was easy to do and they are handy to have in the lab. The arc on the Smith chart has moved halfway around the chart.

The center arc represents the in- ductor, Li. It has been my experience that good antennas are also very sensitive to their source impedance. An antenna is supposed to be the impedance matching circuit between 50 Ohms and Ohms.

In the insert mode, you can place a component on the schematic by simply clicking on the desired component but- ton on the tool bar. Next, we select the main transmission line and decrease its length until the arc connected cnart the circle passing through the simth on the Smith chart sec Figure 12 on page The circle is no longer centered over the origin. Be warned however, this probably will not work.

From this experience we now look to the future with the industry's most trusted and durable range of wireless communication products. Sourcing is given at the end. You might note that the length of the main wjnsmith sion chatr in the previous ex- ample ended up at only MRT's technical consult- ant and a certified electronics technician, is regional communications manager. Note the narrower bandwidth of this match as shown by the return loss plot.

The program is an excellent educational tool as well as a practical tool. Search WorldCat Find s,ith in libraries near you. It can be set to any desired value.
