Mini-Circuits’ ZADC-15-252+ is a coaxial directional coupler providing 15 dB coupling with good VSWR across the 850 to 2500 MHz frequency range. This model is capable of handling up to 8 W RF input power and passing up to 0.3 A DC current from input to output. 18 dB typical directivity allows accurate sampling of signal through the coupled port, and low mainline loss (0.9 dB typical) provides excellent 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.
