The CC-610E from Microlab is a Directional Coupler that operates from 617 to 5925 MHz. It provides a nominal coupling of 10 dB with directivity of more than 17 dB. This coupler can handle an average input power of 300 W and a peak input power of up to 1 kW. It has a PIM of -161 dBc (tested with 2x +43 dBm) and a VSWR of less than 1.3:1. The coupler is available in a module that measures 5.61 x 1.72 x 1.10 inches with 4.3-10 (f), 4-hole flange triplate connectors and is ideal for optimizing power distribution required in 5G FR1 passive distributed antenna systems (DAS). It is ASTM B117-rated and has cleared the salt fog test for up to 720 hrs.
