Single directional couplers offered by Nortec RF cover the frequency range 0.35 - 2 GHz. The uni directional couplers offer low loss and high directivity.
Single couplers sample either the forward or reverse signals. All the directional couplers listed below come with standard N(F) connectors on all ports. However, our
customers can choose SMA(F) or combination of N/SMA connectors on all ports. Please specify your
connector requirements if it is different than the standard N(F).Click the RFQ button for a quotation for quantities above 5. Please call to place an order.
Most of the models are also
available as Bi-directional. Ask about the high peak power versions of the directional couplers listed below, up to 5kW
