A modular approach to design a full three‐way 8 to 18 GHz MMIC active circulator

Abstract

A modular approach to design full three‐way active circulator is presented. Derived S‐parameters for the modular design approach illustrates that broadband performance can be achieved with broadband performance modules. A full three‐way 8 to 18 GHz MMIC active circulator was designed and fabricated with broadband feedback amplifiers and broadband 180° hybrids. © 2012 Wiley Periodicals, Inc.
