15dB Directional Coupler

Rev : P1 | Rev date : 31 Jan 2025

PRODUCT DESCRIPTION

RFS CDS*-43 Directional Coupler Series have been designed for a variety of wireless applications in the frequency band from 350 to 2700 MHz. The wide frequency range allows to use these couplers for multiband wireless Distributed Antenna Systems (DAS) or in combination with RADIAFLEX® radiating cable products. The units couple off a defined fraction of the signal from 6 to 30 dB fulfilling highest RF performance requirements by minimizing reflections or RF loss combined with a compact design. As all passive RFproducts, the CDS**-43 series ensures highest reliability and maintenance free operation.
