Directional Couplers & Bridges

Directional couplers are general purpose tools used in RF and microwave signal routing for isolating, separating or combining signals. They find use in a variety of measurement applications:

  • Power monitoring
  • Source leveling
  • Isolation of signal sources
  • Swept transmission and reflection measurements

A complete line of coaxial single and dual port directional couplers, and bridges for isolating, separating, and combining RF and microwave signals in such applications as power monitoring, source leveling, swept transmission and reflection measurements.
