Directional Couplers


Compact, seam welded packages with radial leads facilitate drop-in mounting techniques. Lumped element design approach provides high directivity over broad bandwidth. Light weight and limited surface area provide ideal device for airborne applications. 


  • Drop-In Package 
  • High Directivity 
  • Broad Frequency Coverage
