Overview

Huawei OMT18Q03 Overview

Huawei OMT18Q03 is a carrier-grade microwave coupler designed for RTN and XMC microwave links that require precise power sampling and monitoring. Operating at 18GHz with a dual polarized waveguide interface, it delivers a 20dB coupling factor and low 3dB insertion loss to maintain link budget in dense urban backhaul, 5G transport, and long-haul networks. Its 10W power handling, 1.2:1 VSWR, and 50 Ohms impedance ensure stable performance across harsh outdoor environments from -40°C to +85°C with compact aluminum construction for easy integration.
