Definition: | a circulator providing a junction between transmission lines
NOTE – Junction circulators may be built in several ways characterized by the symmetry of the junction. To denote these circulator types, the word "junction" is usually omitted and a qualifying prefix used instead. Examples of this practice are the terms "Y-circulator" and "T-circulator", where the capitals are used to describe the type of junction employed.
In the case of waveguide junction circulators, further qualification may be needed, for example as illustrated by the term "H-plane Y-circulator". Such qualifying prefixes should conform with normal waveguide terminology.
