FAQ
A coaxial circulator is a 3-port RF non-reciprocal device that directs microwave signals in one direction. It is widely used in RF front-end systems, radar, and satellite communication links.
It provides signal routing, transmit/receive isolation, and protection of RF amplifiers by controlling signal flow and reducing reflected power in microwave systems.
Yusntech coaxial circulators support wide frequency ranges from VHF, UHF to microwave bands, commonly used in L/S/C/X/Ku-band RF systems for communication and radar applications.
They are widely used in radar systems, satellite communication, wireless base stations, RF testing equipment, and microwave transmitter/receiver modules.
Insertion loss refers to the signal power loss when passing through the circulator. Low insertion loss is critical for maintaining RF system efficiency and signal integrity.
High isolation prevents unwanted signal leakage between ports, protecting sensitive receiver circuits and improving overall system stability.
Depending on the design, Yusntech circulators support low to high power RF applications, including high-power radar and transmitter systems.
Standard options include SMA, N-type, and other customizable RF connectors to ensure compatibility with different microwave system integrations.
Yes. Yusntech offers OEM and customized RF circulator solutions, including frequency tuning, power handling, connector type, and mechanical design.
Yes, we support OEM/ODM manufacturing for coaxial circulators used in commercial, aerospace, defense, and satellite communication systems.
They are widely used in aerospace, defense radar, satellite ground stations, telecom infrastructure, and RF test & measurement industries.
They redirect reflected signals away from the amplifier, preventing damage caused by reflected power and improving system reliability.
A circulator has three ports for directional routing, while an isolator is typically a two-port device used mainly for one-way signal protection.
Yes, our RF circulators are designed for stable performance in high temperature, high power, and demanding microwave operating conditions.
Selection depends on frequency range, power level, insertion loss, isolation, and connector type. Yusntech provides technical support to help customers choose the optimal RF solution.
