The ZCDC10-E6653 from Mini-Circuits is a Directional Coupler that operates from 6 to 65 GHz. It has a coupling factor of 10 dB and a mainline loss of less than 2.4 dB. This device provides a high directivity of up to 28 dB which allows sampling of input powers with minimal detrimental effects due to output mismatches. The coupler can handle up to 11 W of power and has an excellent I/O return loss of 18 dB that minimizes undesired reflections and amplitude ripples. This RoHS-compliant module is available in a module with 1.85 mm female connectors and is ideal for 5G, mobile, fixed satellite, and lab applications.
