WHY CHOOSE THIS DIRECTIONAL COUPLER?

  • ✔ Multi-Band Coverage – Operates from 0.45 to 40GHz, eliminating the need for multiple narrowband couplers.
  • ✔ Test Without Disruption – 10dB coupling enables accurate signal sampling or injection with minimal impact on the main signal path.
  • ✔ Ideal for High-Power Setups – Handles up to 20W 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

Optimized for high-frequency RF instrumentation, this ultra-wideband directional coupler operates from 0.45 to 40 GHz. Featuring a 10 dB coupling factor and 12 dB minimum directivity, it allows for accurate signal monitoring across an expansive bandwidth. With a 1.50:1 max VSWR and low insertion loss of 2.7dB max, it ensures minimal signal degradation. Designed for high-power resilience, it supports up to 20W CW and 3000W peak power handling.
