Determine the impedance of a load at the end of a transmission line. Identify impedance-matching component values from the Smith chart. Most of you have probably heard of the Smith chart.

Impedance matching is one of the perpetual confusions for new electronics students, and for good reason: the idea that increasing the impedance of a circuit can lead to more power transmission is ...

The impact of poor impedance matching on a transmitter is a high standing wave ratio (SWR) that will result in lost power (wasted in the transmission line). In fact, the high SWR may actually ...

These coiled transmission lines are connected in parallel at the low impedance ... 3 in long, μ = 125 ferrite. The impedance ratio, when matching 50 Ω (unbalanced) to 12.5 Ω (balanced and floating), ...

For R1 = 5.1 KΩ, R2 will be 43.2 KΩ. As an example, the values R1 = 56.2 Ω and R2 = 475 Ω can be selected to match the transmission line impedance at the cost of signal swing drop by half. Finally, ...

In practical terms, low-frequency wiring is generally considered to be ‘safe’, while higher frequency circuits require special considerations, including impedance (Z) matching. Where the cut ...
