Mini-Circuits’ ZGBDC20-33HPD+ is a high-power, wideband bi-directional coupler providing 20 dB coupling
with good coupling flatness across the 300 to 3000 MHz frequency range. This model is capable of
handling up to 250W RF input power and passing up to 3.0A DC current from input to output. 20 dB typical
directivity allows accurate sampling of signal through the coupled port, and low mainline loss (0.15 dB
typical) provides excellent transmission of signal power from input to output. The coupler comes housed
in a rugged, IP67 weatherproof case (5.58 x 2.50 x 1.00”) with 7/16 DIN connectors.
