As RF systems migrate toward higher integration and miniaturization, Surface Mount Technology (SMT) microstrip circulators and isolators have become a crucial enabler for compact front-ends. Hzbeat’s SMT series provides non-reciprocal signal routing in a form factor suitable for automated assembly lines, reducing assembly costs while maintaining professional-grade isolation and insertion loss performance.

• Compact SMT package for high-volume automated PCB assembly.
• Low insertion loss (≤0.6 dB typical) and high isolation (≥18 dB typical).
• Stable operation over −55 °C to +85 °C.
• Available in both T-junction and Y-junction topologies.
• Ideal for phased arrays, 5G base stations, and satcom terminals.

The following table summarizes representative models from Hzbeat’s SMT microstrip circulator line.

Specs are representative; always confirm the latest datasheet on the product page.

• 5G Base Stations: Compact SMT packages simplify RF front-end integration in massive MIMO radios.
• Satcom Terminals: On-the-move and fixed terminals benefit from automation-ready packaging.
• Defense & Aerospace: SMT circulators provide reliable isolation in tight phased-array modules.

• SMT vs Typical: SMT emphasizes manufacturability and compactness, while typical offers larger outlines and more power handling.
• SMT vs Miniaturized: Both emphasize size reduction, but SMT also prioritizes ease of assembly in volume production.
• SMT vs Broadband: Broadband covers wider frequency spans, while SMT prioritizes packaging and production efficiency.

With accelerating deployment of 5G and satcom infrastructure, demand for SMT-compatible RF components continues to rise. By offering compact, reliable, and automation-ready circulators and isolators, Hzbeat positions itself as a supplier of choice for OEMs and integrators worldwide.

Q1: Why choose SMT circulators?

They enable direct pick-and-place PCB assembly, reducing cost and improving consistency.

Q2: Are CW and CCW versions available?

Yes, Hzbeat supplies both rotation directions depending on system routing needs.

Q3: What about high-volume production?

SMT outlines are designed for scalable, automated production and quality control processes.
