FAQ

Q: What is the difference between WG Probe Coupler and a directional coupler?

A: WG Probe Coupler uses a probe mechanism for non-contact coupling, offering higher precision and lower insertion loss. Directional couplers typically rely on coupled transmission lines and may have higher insertion loss.

Q: Can WG Probe Coupler operate in high-humidity environments?

A: Yes. The industrial-grade model features an IP67 protection design and can operate stably in environments with up to 95% relative humidity. A salt spray-resistant version is also available for marine applications.

Q: How do I select the right coupling level for my application?

A: Choose the coupling level based on the required signal sampling ratio. For example, a -30dB coupler extracts 0.1% of the input power. Contact us for customized solutions.
