Application of short linear transformers in multifrequency matching

In microwave circuits the source and load impedance must match for maximum power transfer. This can be achieved using an impedance matching network utilizing several different techniques. The short linear transformer (SLT) is a method which uses transmission lines of alternating impedances with calculated lengths for the desired frequency. This method has been expanded for multi-band applications of up to four frequencies. These designs are demonstrated in this project. The SLT proves to be shorter than comparable methods with a preferred response. Also, the design only requires transmission lines of the same impedance as the source and load.
