Directional Couplers

Pasternack directional couplers are passive devices that couple part of the transmission power in a transmission line. Our directional couplers provide the bandwidth, high directivity and higher power that engineers need for their most demanding application designs. RF directional couplers often use two transmission lines set close together so that energy passing through one is coupled to the other. Many Pasternack directional couplers are RoHS and REACH compliant.


Pasternack's RF directional couplers are available with N or SMA connectors and 6 dB, 10 dB, 16 dB, 20 dB, 30 dB and 35 dB coupling values. Power ratings of our typical and high power directional couplers range from 25 Watts to 70 Watts. Directional coupler frequency range of this product design is from 1 GHz to 8 GHz.


Our ISO 9001:2008 registered manufacturing facility in Irvine, Ca. ships all directional coupler products the same day from the deepest, broadest inventory of microwave and RF components available. Exceptional customer service and technical support are available to support our customers on directional coupler questions.
