MULTI-PORT AMPLIFIER AND METHOD FOR CONTROLLING THEREOF

摘要

The present invention provides a multi-port amplifier which adopts a pair of SP4T switches and a pair of hybrid couplers in order to flexibly adjust an amplification mode. By using the proposed invention, the limited system flexibility and reconfigurability due to fixed input and output relations are overcome regardless of a component failure in a system. Moreover, signal amplification based on effective signal distribution and combination can be consistently performed according to various port configurations by different switching modes. Thus, the overall practicality of outputs comparing to the conventional multi-port amplifier can be effectively increased within an available lifespan of the system.
