Impedance Transformation
There are several methods for matching circuits by means of impedance transformation. Chapter 6 illustrates the use of a stub in parallel with a high-frequency transmission line. The problem in this section illustrates an in-line method using an L-section. Ryder 17 gives many additional examples, including T-section, exponential line, T-network, and tapped resonant circuit.
Problem 2-15: IMPEDANCE TRANSFORMATION
Q:
For the circuit shown below, find the load-section parameters in order to match the load to the generator for maximum power transfer.
Answers
Q:
Refer to the section on resonance in Chapter 1. This problem fits the case in which R L > R g. Therefore, Z 1 is an inductor L and Z 2 is a capacitor C the values of which are calculated as follows:
