Outer circle parameters Data Matrix Scanner In None Using Barcode Control SDK for Software Control to generate, create, read, scan barcode image in Software applications. Making Data Matrix 2d Barcode In None Using Barcode printer for Software Control to generate, create ECC200 image in Software applications. The standard Smith chart shown in Fig 44C contains three concentric calibrated circles on the outer perimeter of the chart Circle A has already been covered and it is the pure reactance circle The other two circles define the wavelength distance (B) relative to either the load or generator end of the transmission line, and either the transmission or reflection coefficient angle in degrees (C) There are two scales on the wavelength circle (B in Fig 44C), and both have their zero origin on the lefthand extreme of the pure resistance line Both scales represent onehalf wavelength for one entire revolution, and are calibrated from 0 through 050 such that these two points are identical with each other on the circle In other words, starting at the zero point and travelling 360 around the circle brings one back to zero, which represents onehalf wavelength, or 05 Although both wavelength scales are of the same magnitude (0 050), they are opposite in direction The outer scale is calibrated clockwise and it represents wavelengths toward the generator; the inner scale is calibrated counterclockwise and represents wavelengths toward the load These two scales are complementary at all points Thus, 012 on the outer scale corresponds to (050 012) or 038 on the inner scale Recognizing ECC200 In None Using Barcode reader for Software Control to read, scan read, scan image in Software applications. ECC200 Drawer In C# Using Barcode drawer for .NET framework Control to generate, create DataMatrix image in Visual Studio .NET applications. 106 The Smith chart The angle of transmission coefficient and angle of reflection coefficient scales are shown in circle C in Fig 44C These scales are the relative phase angle between reflected and incident waves Recall from transmission line theory (see Chap 3), that a short circuit at the load end of the line reflects the signal back toward the generator 180 out of phase with the incident signal; an open line (ie, infinite impedance) reflects the signal back to the generator in phase (ie, 0 ) with the incident signal These facts are shown on the Smith chart by the fact that both scales start at 0 on the righthand end of the pure resistance line, which corresponds to an infinite resistance, and it goes halfway around the circle to 180 at the 0 end of the pure resistance line Note that the upper halfcircle is calibrated 0 to +180 , and the bottom halfcircle is calibrated 0 to 180 , reflecting indictive or capacitive reactance situations, respectively Data Matrix ECC200 Encoder In VS .NET Using Barcode generator for ASP.NET Control to generate, create ECC200 image in ASP.NET applications.

There are six scales laid out on five lines (D through G in Fig 44C and in expanded form in Fig 45) at the bottom of the Smith chart These scales are called the radially scaled parameters and they are both very important, and often overlooked With these scales, we can determine such factors as VSWR (both as a ratio and in decibels), return loss in decibels, voltage or current reflection coefficient, and the power reflection coefficient The reflection coefficient is defined as the ratio of the reflected signal to the incident signal For voltage or current: = and = Iref Iinc [416] Eref Einc [415] Data Matrix Maker In None Using Barcode maker for Software Control to generate, create Data Matrix ECC200 image in Software applications.
