High Performance Two Hole RF Directional Coupler

Directional couplers play an essential role in RF signal sampling, power monitoring, and system protection. Our RF directional couplers are engineered for stable, broadband coupling performance while maintaining low insertion loss and excellent directivity—making them ideal for modern communication systems, test equipment, and radar modules.

Compared with the older generation of two-hole couplers, our updated product line offers improved mechanical strength, tighter tolerance control, and more consistent performance over wide temperature and frequency ranges. Whether you need a compact Two hole directional coupler for embedded RF boards or a custom-designed Coupler for demanding microwave platforms, we provide reliable and scalable solutions.

Why Choose Our Directional Couplers?

Stable & Accurate Coupling

Each coupler is designed for precise signal sampling, with consistent coupling values across its operating bandwidth. This ensures higher accuracy in measurement and monitoring circuits.

Low Insertion Loss

Optimized internal structure minimizes energy loss, helping maintain overall system efficiency—an important advantage for high-frequency transmission lines and RF Components in base stations or microwave front-ends.

High Directivity

Our RF directional coupler series offers strong isolation between ports, improving the ability to detect forward and reflected power without significant distortion.

Broad Frequency Compatibility

Available in narrowband and wideband options, supporting applications from VHF/UHF to microwave ranges.

Compact & Rugged Mechanical Design

The classic two-hole directional coupler housing provides stable mounting, excellent thermal conduction, and durability suitable for harsh industrial and communication environments.
