Dual Directional Couplers

Pasternack dual directional couplers (also known as bi-directional couplers) are passive devices that couple part of the transmission power in a transmission line. Our dual directional couplers provide the bandwidth, high directivity and higher power that designers need for their most demanding applications. RF dual directional couplers often use two transmission lines set close together so that energy passing through one is coupled to the other. Many Pasternack bi-directional couplers are RoHS and REACH compliant.


Dual directional couplers from Pasternack are available with SMA connectors and 10 dB, 20 dB and 30 dB coupling values. Power ratings for our dual directional couplers range from 10 Watts to 10 Watts. Frequency ratings for our bi-directional couplers range from 1 GHz to 8 GHz.
