N-way switchable power combiner having matched transmission lines according to the number of combined channels

摘要

The present invention, in the conventional power transmission of the power combiner according to the technology if the path can change as the user as compared to being a mismatch occurs in the impedance of the line desired power transmission path according to the switching power combiner for use in a base station of a variety of communication system not only the number can vary, but has a characteristic impedance of the line is also matched.; Conventional switching power combiner according to the technology, but also a problem that a bad matching state of the line by changing the number of paths power transfer can synthesizable power transmitting path restriction, so the performance is considerably reduced, the present invention provides an impedance in accordance with the number of paths passing power to be synthesized the matching of various kinds of wireless communication systems to in the power transfer, or the need to increase or decrease the number of paths effective switching of the hydro-power transmitting path, without affecting the system in case of failure in some of the paths by providing the switching device can be selectively connected with the line it is possible to provide a power combiner which is easy to configure and change the system.
