Circulators, Isolators, and Directional Coupler

In this course we will cover conceptually how circulators, isolators, and directional couplers function. We will also discuss how these devices are used. This course does not get into the level of detail sufficient to be able to design the devices described, that is to be covered in the advanced course. The idea is to give you the general background required to understand conceptually how these devices work, and what they are used for.

• Summary

This course requires at least an understanding of basic algebra, and has as a prerequisite of INST400 RF and Microwave Devices and Instrumentation. Although not a prerequisite it may be useful to also take EE104 Introduction to RF/Microwave Concepts.
