RF Circulators

RF Circulators are passive, non-reciprocal RF/microwave components used to control the direction of signal flow between multiple ports. They route energy sequentially from one port to the next while providing isolation in the reverse direction, helping manage interactions between connected RF blocks.

Within Wireless & RF Semiconductors, RF circulators are commonly treated as supporting RF front-end components that assist with signal routing and isolation in high-frequency signal paths.

• Non-reciprocal behavior: Signal transmission depends on direction, enabling controlled routing.
• Multi-port signal routing: Typically arranged to pass signals from one port to the next in a defined order.
• Isolation function: Helps reduce undesired coupling or reflections between interconnected RF stages.
