SWITCHABLE POWER DIVIDER/COMBINER AND FREQUENCY ALLOCATION SYSTEM ADOPTING THE SAME

摘要

And a power divider of the present invention is a general high frequency and to the first input transmission line for receiving a radio signal, a second input for receiving a diversity signal through the second input port transmission line via the first input port, first in first input transmission line in and with the first and second transmission line that branches off into two categories, the first and a the second transmission line to the third, and the fourth transmission line, the first and second transmission lines respectively connected to the first and second output port, by isolation resistor, first input transmission line coupled between the first and is formed in a bifurcation of a second transmission line, the first of each of the formed or cut off the path between to the first or the second transmission line to the first input transmission line , the second switch, and a connection between the connection with the in both ends of the isolation resistance in each of the first or the second transmission line to the third, the fourth and the second transmission line to the second input transmission line in the switch, a branch point that on / off according to such a fifth switch and a mode of operation to form or block 1 to the fifth switch A is a controller for controlling the switching operation. It also implements the frequency allocation of the mobile communication system according to the present invention using such a power combiner.
