Dual (Bi) Directional Couplers
-
Pasternack dual directional coupler (also known as bi-directional coupler) series are passive devices that couple part of the transmission power in a transmission line. Our dual directional coupler components 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 coupler items are RoHS and REACH compliant. Couplers that are dual directional from Pasternack are available with SC, SMA and Type N connectors. This dual/bi directional series is offered in 10dB, 20dB, 30dB, 40dB and 50dB 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. Like the other over 40,000 RF, microwave and millimeter wave components from Pasternack, our dual (bi) directional coupler series is in-stock. Not only our these couplers in stock, they also will ship the same-day as they are purchased.
