M2 Global Technology's Senior Scientist Dr. Anthony Edridge will present a free seminar on Application Principles for Circulators and Isolators during IMS 2011 in Baltimore. The seminar will be held on Thursday, June 9, at 11:50 AM in Booth 413 in the Exhibition Hall. Also, check out M2's latest product releases for passive microwave components in Booth 2509.

The presentation on circulators and isolators is part of Microwave Application and Product Seminars (MicroApps). Since its practical realization in 1959, the Ferrite Junction Circulator has found numerous applications in microwave systems. This presentation provides easy-to-understand concepts for non-technical individuals, as well as technical details useful for design and component engineers.

The circuit functions of circulators and isolators will be described using simple concepts and drawings. Various construction methods are outlined for the different application environments of waveguide, coax, and micro strip. Following a brief description of operational principles, examples will be given of how ferrite devices are used.

Ferrite devices possess certain electrical properties that must be specified in order to incorporate them correctly in any microwave circuit. A description of these parameters with preferred values will be provided as a guide for component selection. Design considerations will be presented for the application engineer who may have unique requirements such as high average and high peak power, low intermodulation distortion (IMD), dual junction and attenuator terminations.
