Mini-Circuits’ ZUDC30-83-S+ is a coaxial directional coupler which provides 30 dB coupling with outstanding flatness across the 0.3 to 8 GHz frequency range. This model is capable of handling up to 50W RF input power and passing up to 1A DC current from input to output. 29 dB typical directivity allows accurate sampling of signal through the coupled port, and low mainline loss (0.4 dB typical) provides excellent transmission of signal power from input to output. The coupler comes housed in a rugged, compact aluminum alloy case (6.0” x 0.73” x 0.50”) with SMA connectors and supplied termination for the coupled port on the return path.
