Transmission Line Transformers. Questo articolo non è disponibile.Transmission Line Transformers

This work establishes a foundation for understanding the theory and design principles of the transmission line transformer. It reviews the work of Guanella and Ruthroff and compares their techniques for obtaining a broad-band transformer with a 1:4 impedance transformation ratio, then analyzes low- and high-frequency responses of transformers, and examines transformer parameters for low- and high- impedance applications. Unbalanced-to-unbalanced transformer designs are discussed, and materials and power ratings and simple test equipment are covered. This fourth edition contains new chapters on transmission line transformers, power combiners and mixer transformers, and equal-delay transformers. There is no subject index. The author, retired from AT&T Bell Laboratories, is a technical advisor for the American Radio Relay League. Annotation c. Book News, Inc., Portland, OR (booknews.com)
