The CK-16LE and CK-17LE 4-port Directional Couplers are a tapered strip line design covering from 617 to 3,800 MHz for CBRS and Band43 applications. Units couple off a defined fraction of signal with minimal reflections or loss.The extremely wide frequency range allows use with mul-tiband antennas, leaky cable systems and wireless base sta-tions. With minimal solder joints and a low loss dielectric, the dissipative loss has been minimized and reliability enhanced. Mounting brackets are included.
