Product Introduction:

An RF coaxial circulator is a multi-port, non-reciprocal device that employs a coaxial interface. Its core feature is the ability to achieve directional circulating transmission of RF signals among its ports. It offers advantages such as ease of connection, high power handling capability, and excellent performance, and is commonly used for signal separation and system protection.
Product features:

Directed cyclic transmission: The signal flows unidirectionally in a strictly fixed sequence (e.g., port 1 → 2, port 2 → 3, port 3 → 1). This is the fundamental operating principle.

Coaxial Interface: Uses standard coaxial connectors (such as SMA and N-type), enabling quick and reliable connections to cables and test instruments, and facilitating easy installation and maintenance.

Diverse functionalities: The core function is to separate and route signals—for example, in radar systems, directing the transmitted signal to the antenna while simultaneously routing the signal received by the antenna to the receiver, thereby enabling shared transmit-and-receive operation.

Performance balance: Typically featuring low insertion loss and high isolation, these devices can handle medium to high power levels and are highly versatile fundamental components in RF systems.

Widely applicable: Commonly used in scenarios such as communication base stations, radar RF front ends, and test and measurement systems—anywhere signals need to be circulated and isolated. By connecting a matching load to one of its ports, it can be used as an isolator.
