The CK-19 Directional Couplers are tapered stripline design covering from 694 to 3,600 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.
