Abstract

Several elements for 2G/3G Base Station have been developed in order to provide a dual operation with the same unit. The main equipment developed by RYMSA following the philosophy of duality is a Band Tower Mounted Amplifiers (TMA) which covers all the band Tx and Rx 2G/3G. In the unit there are two transmission paths for 2G and 3G, and two reception paths for 2G and 3G with Rx-bypass in failure case. The equipment is made up of two units, each one has one Tx path for 2G and other for 3G and the same for Rx. All the signals that go to the same connector are multiplexed by direct unions with bar-line technology. Cross-coupling, resonators and inductive “diagonal” couplings are used to adjust the different filters. Other equipment designed for this application is the “Combined Diplexer and Bias Tee”, which function is integrate in a 2G/3G station the signals coming from 2G and 3G equipment, the equipment power supply and monitoring and control signals of the system. A Power Distribution Unit is associated as well to this group. This PDU provides the power supply to the active equipment in the tower, as well as to monitoring the state of the TMA’s in a station and centralize the remote communications.

Sumario

Han sido desarrollados una serie de elementos para Estaciones Base 2G/3G con el fin de proporcionar una operación dual utilizando una sola unidad. El principal equipo desarrollado por RYMSA siguiendo la filosofía de dualidad es un Amplificador para montaje en torre (TMA) el cual cubre ambas bandas de frecuencia, 2G y 3G. La unidad proporciona dos caminos para transmisión en 2G y en 3G, así como dos para la recepción de 2G y 3G con Rx-Bypass en caso de fallo. El equipos está formado por dos unidades totalmente idénticas y cada una de las cuales tiene un camino de transmisión para 2G y otro para 3G y, los mismo para recepción. Las señales que van a un mismo conector están multiplexadas por uniones directas de bar-line. Para el ajuste de los diferentes filtros se utilizan acoplos cruzados, resonadores y acoplos “diagonales” inductivos.

 Se ha diseñado para esta misma aplicación un “Diplexor Combinado y Bias T” cuya función es integrar en una estación base 2G/3G la señales procedentes de los equipos de 2G y 3G, la alimentación de estos equipos y las señales de monitorización y control del sistema.

La PDU proporciona la alimentación a los equipos activos en la torre, así como el estado de monitorización de los TMA’s en una estación y la centralización de la s comunicaciones remotas.
