Directional Couplers


This series utilizes stripline circuit design in a small package while maintaining optimal electrical performance values. Frequency response is flat over the octave band. The design also permits usage as a bi-directional coupler, allowing the sampling of incident and reflected power. Design package accommodates SMA, N, BNC and TNC connectors. Design modification may be necessary for non-SMA connectors. 


  • Flat Frequency Response
  • Multi-Octave Band Coverage
  • Compact Size
  • Standard SMA Connectors (N, BNC, TNC optional)
