DIVIDER/MIXER-COMBINATIONAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a divider/mixer-combinational device that can be used as a divider and as a mixer as well.SOLUTION: The divider/mixer-combinational device comprises: an input/output terminal; two or more division/input terminals; a dividing/mixing circuit; an input monitor terminal; an output monitor terminal; a branching transformer and attenuators. Possible uses are a divider where an input signal to the input/output terminal can be divided by the dividing/mixing circuit and divided among the two or more division/input terminals, and a mixer where input signals from the two or more division/input terminals can be mixed by the dividing/mixing circuit and output to the input/output terminal. The branching transformer has an input side inserted between the input/output terminal and the dividing/mixing circuit and an output side inserted between the attenuator connected to the input monitor terminal and the attenuator connected to the output monitor terminal, and the attenuators are inserted between the output side of the branching transformer and the input monitor terminal and between the output side of the branching transformer and the output monitor terminal, respectively. The output monitor terminal and the input monitor terminal can be terminated by a dummy resistor during the use as the divider and during the use as the mixer, respectively.
