Parsippany, N.J. Microlab/FXR, a wholly owned subsidiary of Wireless Telecom Group, Inc., has introduced its CK-70N series of directional couplers for wireless applications. These directional couplers cover the frequency range of 380 to 2,700 MHz including the Tetra/PMR bands, cellular, PCS and UMTS bands in a single unit.
The CK-70N directional couplers are designed using a multi-section, airline design for low loss of less than 0.1 dB, flat frequency response and 200 W of through line power. The wide frequency range and low passive intermodulation of this design allows use with multi-band antennas and leaky cable as well as higher power cellular systems when PIM issues become critical.
The CK-70 series is available in 3-port models with coupling values of 6, 10, and 15 dB. Four-port versions are also available.
