Drop in Circulator
An RF embedded circulator is a multi-port, non-reciprocal device packaged in surface-mount or integrated form. Its key feature is that it can be directly embedded into PCB circuits, enabling directional circulation and separation of signals to meet the demands of high-density integration and miniaturization in devices.
An RF embedded circulator is a multi-port, non-reciprocal device that employs surface-mount or integrated packaging. Its core feature is its ability to be directly embedded in PCB circuits, enabling directional circulation and separation of signals, thereby meeting the demands for high-density integration and miniaturization of devices.
Its core features include:
- Miniaturization of the structure: Utilizing flat, compact surface-mount device (SMD) packaging, the size and weight are significantly smaller than those of coaxial circulators.
- Easy to integrate at high density: It can be directly mounted onto PCBs via SMT technology without the need for cable connections, making it a key enabler for miniaturizing microwave modules (such as 5G AAUs and mobile phone RF front-ends).
- The core functionality remains unchanged: The circulator’s fundamental characteristics are still preserved, enabling signals to circulate directionally among ports in a fixed sequence (e.g., 1→2→3→1), which is used for signal separation and transmit/receive switching.
- Suitable for automated mass production: Perfectly compatible with PCB manufacturing processes, significantly boosting production efficiency and consistency while reducing assembly costs.
- Performance trade-offs: Compared to coaxial structures, this design typically has lower power capacity and heat dissipation capability; however, it is sufficient to meet the application requirements of most highly integrated devices.
