SMD Circulator(SMT), Surface Mount Device

Frequency up to 40GHz.

SMD Circulator (SMT) is a compact and versatile component designed for seamless integration into surface mount assemblies.

Product Details

Characteristics and Applications

This circulator offers high isolation performance and efficient signal routing in modern communication systems, radar systems, and RF front-end modules. Its compatibility with SMT assembly processes makes it an ideal choice for applications where space-saving and efficient assembly are essential. The SMD Circulator (SMT) provides reliable signal routing and isolation while enabling easy integration into surface mount technology-based circuitry.

Key Features & Advantages

1. Miniaturization & Light Weight: The use of LTCC and SMT technology results in a much smaller volume and lighter weight compared to traditional waveguide or connectorized circulators. This is ideal for equipment with strict space and weight constraints (e.g., mobile phones, drones, phased array radar T/R modules).
2. High Reliability: All-solid-state structure with no moving parts, offering strong resistance to vibration and the ability to withstand harsh mechanical and environmental conditions. The ceramic and metal packaging provides excellent hermeticity and thermal stability.
3. Suitable for Automated Production: The SMD package is perfectly compatible with PCB assembly processes, allowing for rapid, low-cost, high-consistency assembly via SMT production lines, significantly improving manufacturing efficiency
4. Excellent RF Performance:
   • Low Insertion Loss: Very minimal signal loss in the forward path (typically <0.5 dB), ensuring high signal transmission efficiency.
   • High Isolation: High attenuation in the reverse path (typically >20 dB), effectively preventing signal reflection and interference.
   • High Return Loss / Low VSWR: The Voltage Standing Wave Ratio at each port is typically very low (e.g., <1.25), indicating good port matching and low reflection.
5. Broadband Performance: Can be designed to operate stably over a relatively wide frequency band, covering a broad range of applications from hundreds of MHz to tens of GHz.

Typical Applications

• Mobile Communications: 4G/5G/6G base stations, small cells.
• Radar Systems: Military, meteorological, automotive radar.
• Satellite Communication: VSAT, satellite/ground terminals.
• Test & Measurement Equipment: Vector Network Analyzers, signal sources, etc.
• Internet of Things (IoT) Devices.
