Description

The Kathrein 78211055, also identified by part number 469869A, is a high-performance Smart Bias Tee designed for carrier-grade telecommunications infrastructure. This component is engineered to operate across a broad frequency spectrum from 690 MHz to 2700 MHz, supporting a wide range of cellular standards, including LTE and UMTS. Its primary function is to inject or extract DC power and AISG (Antenna Interface Standards Group) control signals into or from a coaxial feeder cable, enabling the remote management and powering of Tower Mounted Amplifiers (TMA) and Remote Electrical Tilt (RET) antennas.Technically, the 78211055 facilitates the transmission of DC voltage (+8 to +32VDC) from the Base Transceiver Station (BTS) side to the antenna side via the RF center conductor. It features an integrated modem for AISG signal processing, ensuring transparent communication between the system controller and the mast-head equipment. The device is optimized for low insertion loss and excellent return loss across its entire operating range, maintaining high signal integrity for the primary RF traffic. Built with a robust, weather-resistant housing, it is suitable for both indoor and outdoor deployments. The unit incorporates advanced lightning protection and is designed for superior passive intermodulation (PIM) performance, which is critical for maintaining network capacity in multi-carrier environments. It typically utilizes 7/16 DIN or similar high-quality connectors to ensure secure and reliable electrical connectivity in demanding mobile network sites.
