This fourth edition contains all the valuable information from earlier editions:
the classic 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 that can be obtained with transmission transformer techniques. Three
new chapters cover:
Transmission Line Transformer Efficiency
Notes on Power Combiners and Mixer Transformers
Equal-Delay Transformers
The new information includes observations and analyses by Jerry Sevick intended
to clarify the principles behind the operation of these transformers. An entirely
new chapter presents the family of equal-delay transformers that enable designers
to obtain the benefits of transmission line transformer performance with a wider
range of transformation ratios. Written by Gary Breed, K9AY, this chapter maintains
Sevick’s practical tone with construction details and performance evaluation
of a 50–to–75-ohm equal-delay transformer.
312 pages, hardcover. Fourth Edition, © 1996, 2001 by Noble Publishing Corporation.
