摘要： An apparatus for detecting an operating characteristic mismatch at an output of an amplifier by using a replica circuit is presented. In one exemplary case, a detected voltage difference at the output of the two circuits is used to drive a tuning control loop to minimize an impedance mismatch at the output of the amplifier. In another exemplary case, the replica circuit is used to detect a fault in operation in a corresponding main circuit. A method for detecting a load mismatch in a main RF circuit using the replica circuit is also presented.

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.
