Precise Signal Direction Control

Enhancing System Stability in UWB Applications

In high-frequency RF systems, signal reflection and interference are critical factors that can significantly impact performance.

WOKEN Technology introduces its RF Coaxial Circulator & Isolator Series, specifically designed for UWB (3.1–10.6 GHz) applications,

delivering excellent signal isolation and directional control to ensure stable system operation.

Essential Components for UWB Applications

In UWB systems, due to ultra-wide bandwidth and pulse-based signal transmission, components require high frequency consistency and superior reflection control.

Circulators and Isolators are indispensable non-reciprocal devices:

•  Circulator (3-port): Controls unidirectional signal flow (Port 1 → Port 2 → Port 3)
•  Isolator (2-port): Prevents reflected signals from returning, protecting critical components
• An isolator is essentially a circulator with a matched termination, effectively absorbing reflected energy

Key Features

 Optimized for UWB Band

• Supports 3.1–10.6 GHz ultra-wideband applications
• Ideal for pulse-based and broadband signal environments

High Isolation & Low Loss Design

• High isolation ensures proper signal direction control
• Low insertion loss maintains signal integrity
• Excellent VSWR performance minimizes reflections

✔ High isolation and low loss are the core performance indicators of circulators and isolators

Stable Non-Reciprocal Performance

• Designed with ferrite materials and magnetic biasing
• Enables unidirectional transmission and reflection suppression

Flexible Coaxial Interface Options

• Supports standard RF connectors such as SMA / N-type
• Easy integration into various RF and test systems

Applications (Aligned with UWB)

This product series is ideal for UWB-related applications:

• Indoor positioning systems (UWB RTLS / Tags)
• Short-range sensing and automotive radar (SRR)
• Industrial automation and asset tracking
• Short-range high-speed wireless communication
• UWB testing and measurement systems

It can also be applied in:

• RF test equipment
• Wireless communication module protection and isolation

✔ Circulators and isolators are widely used in communication, radar, and test systems

Built for System Stability

In UWB systems, reflected signals can cause:

• Signal distortion
• System instability
• Damage to power amplifiers

With WOKEN RF Circulators & Isolators, you can:

✔ Suppress reflections effectively
✔ Protect critical components (e.g., power amplifiers)
✔ Enhance overall system reliability
