Smith Chart Tutorial Part 3 - Lumped Matching
For lower frequency circuits, lumped elements are normally used instead of transmission
lines. The rules governing series and shunt capacitors and inductors were given in part 1.
There are two ways to begin matching (1) From the 50-ohm load to the match and (2) From
the match to the 50-ohm load.
(1) 50-ohm load to the match
For this example we will design a lumped matching circuit to match 50 ohms to the optimum
noise match of a FET. In other words we want to present a particular match to the FET in
order to ensure minimum noise. Lets assume that the data
