Waveguide Directional coupler

Directional coupler

Directional coupler
  • High directivity
  • Minimum coupling variation
  • Low VSWR

The DCZ-XXE/Y directional couplers are used for extracting or introducing RF power flow in a transmission line without distortion of signal characteristics. The directional couplers are available in 3, 6, 10, 15, 20 dB coupling values and 30 - 35 dB minimum directivities*. 4-ports directional couplers are available in bi-directional (BDC4-XXE/Y) and dual-directional (DDC4-XXE/Y) configurations.
