Surface Mount Technology Microstrip Circulator

X Band, Ku Band. (8GHz-18GHz)

The Surface Mount Technology (SMT) Microstrip Circulator series is designed for easy integration into surface mount assemblies, providing flexibility for a wide range of electronic applications.
These circulators are characterized by their compact size, high performance, and compatibility with SMT assembly processes.
They are ideal for modern communication systems, phased array antennas, and RF front-end modules where space-saving and efficient assembly are critical. The SMT Microstrip Circulator series ensures reliable signal routing and isolation with seamless SMT-based integration.

Key Features & Advantages

Ultra-Compact and Lightweight: Employs LTCC and integrated design, allowing for very small sizes (e.g., 3.2x2.5x1.2mm) and weights of just a few tenths of a gram, greatly saving PCB space. Ideal for highly integrated modules.
Surface-Mount Package: Compliant with SMT process requirements, can be directly mounted onto PCBs via reflow soldering. Highly suitable for automated, large-scale production, significantly reducing assembly cost and time.
Excellent High-Frequency Performance: The planar structure delivers outstanding performance in high-frequency and ultra-high-frequency bands (e.g., C, X, Ku, Ka bands), with low parasitic parameters and stable performance.
High Reliability: All-solid-state structure, no moving parts, resistant to vibration and shock. LTCC material offers good thermal stability and long operational lifetime.
Excellent Consistency: Manufactured using semiconductor-like processes, offering far better batch-to-batch consistency and product repeatability than coaxial or stripline circulators.

Typical Applications

Radar Systems: Used in T/R Modules to switch between transmit and receive paths, protecting the low-noise amplifier from high-power transmit signals.
Mobile Communication Infrastructure: Isolation of transmit and receive signals in 5G/4G Base Station Massive MIMO antenna systems.
Point-to-Point / Point-to-Multi-point Radios: In microwave relay communication and satellite communication terminals, enabling single-antenna operation for both transmit and receive functions.
Test & Measurement Equipment: Used in equipment like signal sources and spectrum analyzers for signal routing and isolation.
IoT & Drones: Enables efficient RF signal management in devices with stringent size and weight constraints.
