In electrical engineering, a circulator is a passive, non- reciprocal three- or four- port device that only allows a microwave or radio-frequency (RF) signal to exit through the port directly after …

Learn how an RF circulator works, its operational principles, and its applications in RF systems. Explore its use in sharing antennas between transmitters and receivers.

Circulators are non-reciprocal three-port devices that route power sequentially (1/2/3) using ferrite biasing to isolate reflections and protect transmitters. They are used for duplexing, isolating PA …

Our RF Isolators and RF Circulators are predominantly used in telecommunications radios. They protect the equipment from reflected RF power, and they are key to helping reduce …

Pasternack RF circulators are passive 3-port microwave devices which control the signal direction and flow inside of an RF circuit. RF circulators are also unidirectional, but circulate the flow of …

Jul 29, 2025 · In this article, I’ll walk you through the main applications of RF circulators, explain how they work, compare them to isolators, and provide practical selection guidance based on …

Jun 12, 2025 · RF circulators are crucial components in RF engineering, playing a vital role in managing signal flow and providing isolation in various RF systems. In this comprehensive …
