WHY CHOOSE THIS DIRECTIONAL COUPLER?

  • ✔ Multi-Band Coverage – Operates from 0.5 to 18GHz, eliminating the need for multiple narrowband couplers.
  • ✔ Test Without Disruption – 20dB coupling enables accurate signal sampling or injection with minimal impact on the main signal path.
  • ✔ Ideal for High-Power Setups – Handles up to 30W continuous and 3000W peak, supporting power amplifier and antenna testing.
  • ✔ Built-In DC Pass – Bias active components directly without external bias tees or injectors.

PRODUCT OVERVIEW

Designed for wideband RF sampling, this 0.5–18 GHz 20 dB directional coupler delivers low-loss performance with up to 1 dB insertion loss, ≥15 dB directivity, and 1.30:1 max VSWR for low reflection and accurate monitoring. Rated for 30 W CW max and 3000 W peak, it’s a dependable choice for lab, production, and high power RF systems.
