Mini-Circuits’ ZUDC20-83-S+ is a coaxial directional coupler which provides 20 dB coupling with outstand-
ing flatness across the 0.3 to 8 GHz frequency range. This model is capable of handling up to 20W RF
input power and passing up to 1A DC current from input to output. 24 dB typical directivity allows accu-
rate sampling of signal through the coupled port, and low mainline loss (0.7 dB typical) provides excel-
lent 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.
