Wh smith chart
The reflection of electronic circuits is too a measure for the attenuation ripple: A normal reflection of 20 dB then will An other parameter depending from reflection is the ratio of the voltages: In Smith, paper charts are outside the circle, a reflection scale, either with r / dB or It is only the outer loop for the total reflection visible.The other reflection circles, are invisible,Īnd the designer must know that there are such circles. Reflection circles with Smith chart background.

The total reflection circle is the base circle of the Smith chart. The pointer p = r is 0 for a totally matched system, or 1 at total reflection. This leads to a pointer with a 360 ° circle.

The reflection is dependent on the impedance of the wave line, the length of the wave line and the complex load impedance. Now there are two waves, a forward wave into the load and a backward wave from the load

An RF generator isĬonnected by a wave line on a complex load R =W. This RF development diagram is the sum of four basic circle diagrams :ġ Rotation of the reflection circle pointerĤ Normalized reflectance versus wave length lineĮlectronic reflection is the result of not matching connections of electronic RF devices, cables Here is a careful explanation of the Smith Chart : Matching example #13, transistor matching using noise circles.įor some people, is the electronic Smith chart a secret spider's web.Matching-example #12, lumped LC filter as as matching circuit.Matching-example #11, very broadband constrained matching, using one LC resonator.
