RF Couplers

Couplers can be used to monitor a RF signal while adding very little insertion loss to the RF path.  JFW offers resistive couplers and directional couplers.  Resistive couplers are wideband, operate at DC and couple in both directions.  Directional couplers work over a defined frequency band and couple the RF signal in only one direction.  For your specific application, please contact JFW or use our Inquiry Form.

Directional Couplers

• Reactive design
• Couples in only one direction
• Provides isolation from reverse RF signals to coupled port
• Functions at specified frequency band (not at DC)
