This tutorial introduces the theory and practice of transmission line transformers (TLT). In an innovative approach to the subject, Sevick divides TLTs into four classes: TLTs with ratios of 1:1, 1:4, less than 1:4 and greater than 1:4. The first two sections in this course cover 1:1 baluns and 1:4 baluns and ununs, as discussed by Guanella and Ruthroff. Additional sections review TLTs with ratios less than 1:4 and greater than 1:4, such as 1:6, 1:9, 1:12. The course concludes with a discussion of information on diode mixers and power combinerssplitters.

The material covered in this course provides incentive to investigate:

* The application of the latest TLT designs in broadband amplifiers and logic circuits
* The advancement of the theory and broadband response of the TLT
* The research in ferrite materials for high permeabilities with high bulk restivity

Approximate running time is one hour.
