The ZUDC30-5R23-S+ from Mini-Circuits is a Directional Coupler that operates from 0.5 to 2 GHz. It can handle up to 50 W of input power, has a coupling factor of more than 30 dB with 34 dB of directivity. The high directivity of this coupler allows sampling of input powers with minimal detrimental effects due to output mismatches. It has a return loss of 20.8 dB which minimizes undesired reflections and resulting amplitude ripple. The coupler can is available in a module with SMA-female connectors and is ideal for mobile, fixed satellite, lab use, GPS, radar, and radio applications.
