Transmission Line Transformers
(Fourth Edition)
AUTHOR: Jerry Sevick
FORMAT: Hardcover, 304 pages
ISBN: 1-884932-18-5
The fourth edition of this classic text on transmission line
transformers for high frequencies includes new chapters on
transmission line transformer efficiency, power combiners and mixer
transformers, and equal-delay transformers.
The new edition contains all the valuable information from earlier
editions: the clasic techniques of Guanella and Ruthroff as well as
hundreds of real transformers constructed and measured to
establish the practical levels of bandwidth and loss performance.
Readers are encouraged to look beyond the design examples to
learn the basic theory that makes transmission line transformers
different. In most cases, they will have higher performance than
conventional magnetic flux-coupled transformers.
