MICROLAB's CK-10 series of directional couplers is a tapered stripline design covering from 617 – 3,800 MHz. Units couple off a defined fraction of signal with minimal reflections or loss. Each model is available as a four (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).
