Mini-Circuits’ ZADC-13-73-S+ is a coaxial, wideband directional coupler providing 13 dB coupling with good coupling flatness across the 2600 to 7000 MHz frequency range. This model is capable of handling up to 4 W RF input power and passing up to 1.0 A DC current from input to output. 18 dB typical directivity allows accurate sampling of signal through the coupled port, and low mainline loss (0.8 dB typical) provides excel- lent transmission of signal power from input to output. The coupler comes housed in a rugged, compact aluminum alloy case (2.0 x 2.0 x 0.75″) with SMA connectors.
