An ideal circulator has the following S -matrix form: (7.23) if you know the dimensions and requirements you will be able to design it of the circulators, if you know the working of a circulator then it should pretty easy to design and simulate it in HFSS. When the RF signal is applied to port 1, it rotates through the device and will exit via port 2. What is a Microwave Circulator? Although there is no single formal definition of which frequencies constitute microwaves, one widely used definition is that it concerns wavelengths ranging from about one meter to one millimeter with corresponding frequencies between 300 MHz and 300 GHz respectively. The nonreciprocal conversion is obtained in the broken time-reversal symmetry regime, where the conversion of photons from one frequency to the other is enhanced for . Stripline circulator theory and applications from the world's foremost authority. Previous approaches to integrating circulators on chip involve either external driving that requires extra microwave lines or a strong magnetic field that would compromise superconductivity. Among the many topics discussed are microwave switching, circular polarization, planar wye and equilateral triangle resonators, and many others. There are different models of circulators available in the market from different manufacturing companies. Broadband High Power.
