Please Register or call for more information

The CK-10 series of Directional Couplers is a tapered stripline design covering from 617 to 3,800 MHz. Units couple off a defined fraction of signal with minimal reflections or loss. Each model is available as a 4 port coupler.

The extremely wide frequency range allows use with multiband antennas, leaky cable systems and wireless base stations. With minimal solder joints and a low loss dielectric, the dissipative loss has been minimized and reliability enhanced. Mounting brackets are included.

Four port directional couplers are available with LC, LD, LE or LN suffix, (e.g. CK-16LN). For outdoor environments add suffix ‘P’ to Model No. (e.g. CK-16NP).
