UNEVEN TERNARY DISTRIBUTOR

摘要

An unequal three-way divider divides an input signal into three in-phase signals whose power ratio is different between a center and both ends. The unequal three-way divider includes an input terminal, and three output terminals for outputting a three-divided signal respectively, and three transmission lines branched from the input terminal are provided between the input terminal and the three output terminals. The transmission line connected to the center output terminal has a first transmission line which is connected in series and a second transmission line whose electrical length is 1/4 wave length. Two transmission lines connected to the output terminals at both ends have a third transmission line which is connected in series and a fourth transmission line whose electrical length is 1/4 wave length respectively. An absorption resistor is provided between a connection point between the first transmission line and the second transmission line and connection points between the third transmission lines and the fourth transmission lines respectively. An electrical length of the first transmission line or the third transmission line is 1/4 wave length.
