The CK-70N series directional couplers cover frequencies from 380 to 2,700 MHz to support the Tetra/PMR, cellular, PCS, and UMTS bands from a single unit. The couplers use a multisection airline design to achieve a loss of less than 0.1 dB, a flat frequency response, and 200 W of through-line power.
The couplers are available as three-port models with coupling values of 6, 10, and 15 dB, as well as in four-port versions. (Contact Tony Ramsden for price and availability.)
