<P>PROBLEM TO BE SOLVED: To provide a three port power divider/combiner consisting of a directional coupler. <P>SOLUTION: By using a first directional coupler 10 and a third directional coupler 15 which divide an input power into two parts of 1/2, and a second directional coupler 13 which divides an input power into two parts of 1/3 and 2/3, the phase difference between the sum of phase amount β2 of a second line 12 connecting K3 terminal and K4 terminal and a phase amount β3 of a third line 14 connecting K5 terminal and K6 terminal, and a phase amount β1 of a first line 11 connecting K1 terminal and K2 terminal is set to 90°+(180°×N). Consequently, a power input to input terminals Pi1, Pi2, and Pi3 is divided uniformly into three parts of 1/3 and output from output terminals Po1, Po2, and Po3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
