QuickSmith - Free Interactive Open Source Smith chart for Web and Mobile for impedance matching - A Tutorial

The goal is to navigate the blue dot on the Smith chart to the circle going through the center and then use the last component to bring to the 50 Ohm point. See the Large Signal Amplifier …

The examples here mostly application oriented and does not get into theoretical d etails, it is however urged that the user should refer to standard text books for basic concepts on …

These exercises uses basic resistance and reactance to illustrate their mapping on the chart. a) From the Schematic window assign 0 Ohm resistor to a series slot by dragging the resistor …

Decrement the Noise figure until it intersects the 10.55 dB gain circle and .click "Re dr aw" to clean-up the chart. In the bottom of the window change GammaS such that it moves to the …

Constant conductance circles can be drawn by using the show admittance function (Admittance Circles) in the display menu of chart window. Finally we use an open circuit transmission line, …

This example refers to section 4.2 in Motorola's application note AN721. Here Sm ith chart is used to design an input/output matching network for a RF power transistor. Problem: Design a …

AV Gain Circle Step Size [degree]: OP Gain Circle Step Size [degree]:

The examples considered so far have been examined at single frequency. We will now consider impedance matching network for a range of frequencies. One of the interesting aspects of …

After finding the required input and output impedance our next task is to design a suitable network to provid e optimum match. For maximum power the matching circuit should be conjugate of …
