Abstract

A test board is provided including a first branch line including a first portion which receives an input signal and a second portion opposite to the first portion. A plurality of second branch lines branch from the first branch line. Each of the second branch lines include a third portion connected to the second portion of the first branch line and a fourth portion connected to the third portion. A first characteristic impedance of the first portion of the first branch line is different from a second characteristic impedance of the second portion of the first branch line. A third characteristic impedance of the third portions of each of the second branch lines is different from a fourth characteristic impedance of the fourth portions of each of the second branch lines. The second characteristic impedance is equal to a combined characteristic impedance of the third portions of each of the second branch lines.
