Practical Use: Circulators and Isolators

See on Scoop.itKH6JRM’s Amateur Radio Blog

These two devices, related in function and form, are indispensible when working with RF.

Russ Roberts‘s insight:

Thanks to reporter David Hall for this article.  The Practical Use of Circulators and Isolators is a basic tutorial on these vital transmitter components from Doug Irwin, CPBE, DRB, and AMD.  According to Irwin, isolators and circulators are integral parts of HD radio transmitters using the VHF/UHF spectrum.  Engineers use isolators to control intermodulation products.  Junction circulators "direct the signal flow clockwise or counterclockwise, depending on the polarization of the magnetic field."    A good technical tip for the day.
