In today's microwave practice, the directional coupler has become a virtually indispensable measurement tool. It provides a simple, convenient, accurate means for sampling microwave energy without moving parts and without the need for adjustments.

Unlike other methods of power sampling involving probes or coupling loops, the directional coupler also provides the important capability of separating forward from reflected power. By selecting energy traveling only in one direction, accurate VSWR measurements can be made automatically, eliminating the mechanical motion needed with a slotted line.

Attenuation measurements also become more accurate when directional couplers are used since reflection errors are eliminated.

Features:

  • 0.95 to 2 GHz
  • Coupling Coefficient: 20 dB
  • Directivity: 30 Db
  • Insertion Loss: 0.20
  • VSWR: Line Max 1.15
  • Frequency Range: .95 to 2.0 GHz
  • Coupling: dependent on model ordered
  • Minimum directivity: 30 dB
  • Maximum SWR: 1.15 (primary) 1.15 (secondary)
  • Connectors: Type N
  • Shipping weight: 5 lb
  • RF Safety
