About This Part
The Kathrein Smart Bias Tee (SKU: 78211055) is a critical component in modern wireless infrastructure, designed to efficiently combine DC power and RF signals onto a single coaxial cable, or separate them at the receiving end. This intelligent device facilitates the remote powering of active RF components, such as Tower Mounted Amplifiers (TMAs) or Remote Radio Heads (RRHs), directly through the antenna feeder line. By eliminating the need for separate DC power cables, it simplifies installation, reduces cabling complexity, and enhances system reliability in challenging outdoor environments. Operating across a wide frequency range of 690-2700 MHz, this bias tee supports various cellular technologies, including 2G, 3G, and 4G, making it versatile for diverse network deployments. It is engineered to inject DC power from a Base Transceiver Station (BTS) with a voltage range of +8 to +32VDC, ensuring stable and consistent power delivery to remote equipment. The 'Smart' designation often implies advanced features such as remote monitoring or control capabilities, optimizing network performance and maintenance. As a B2B supplier, Revo Distribution Limited offers this Kathrein Smart Bias Tee as part of our commitment to providing high-quality, refurbished telecom and data centre equipment.
