Directional Couplers


Coaxial cable based design approach provides high directivity over broad bandwidths. Design package accommodates SMA, N, BNC and TNC connectors. Design modification may be necessary for N connectors. 


  • Broad Frequency Coverage
  • High Directivity 
  • Connector Options Available
  • Standard SMA Connectors (N, BNC, TNC optional)

Finish: Chemical Conversion Coating per MIL-DTL-5541 Class 3 (optional paint available upon request)
Marking: All units supplied with P/N and date code on polyester label (special marking available upon request)
Electrical Test: All units tested on a Go/No-go basis (plotted data available upon request). Specifications indicated are subject to change. Unless otherwise specified, electrical properties correspond to use with standard SMA connectors. Insertion loss excludes coupled power.
Dimensions: All dimensions are expressed in inches, (1 inch = 25.4mm). All dimensions indicated are subject to change. Unless otherwise specified, tolerances for decimals are ±0.02 for .XX and ±0.005 for .XXX. Tolerances for angles are ±0°30'.
Temperature: Units designed to operate -55° to +85° C.
