CDS20-43-555/6000
Broadband Directional Coupler for Wireless & Indoor Application, 555-6000MHz, 20dB Coupling Loss

Rev : A | Rev date : 04 Jun 2021

PRODUCT DESCRIPTION

RFS' CDS*-43 series of Directional Couplers have been designed for a variety of wireless applications in the frequency band from 555 to 6000MHz. The units couple off a defined fraction of a RF signal from 5 to 30 dB (depending on the model number) with minimal reflections or loss. The broad frequency range is ideally suited for multi-band distributed antenna systems or in combination with RADIAFLEX® radiating cables.
