Abstract

In accordance with standard practice, the word "hybrid' as used here also means "hybrid power divider/ power combiner? The hybrid is ideally a four-port, lossless, reciprocal, and symmetrical network in which the vector sum of two sinusoids, each incident on one of two ports, appears at a thud port, and the vector dif- ference of the incident sinusoids appears at the fourth port. Hybrids are used for linear power division, power combining, and phase shitlmg in larger functional blocks such as mixers, phase comparators, and other applica- tions requiring vector processing of audio, W and micro- wave signals.
