Four-phase phase converter

摘要

In four microstriplines disposed close such that they are coupled with each other, the left-hand end of the third microstripline serves as an input, the left-hand ends of the first and second microstriplines and the right-hand ends of the first and fourth microstriplines serve as outputs, and the right-hand end of the second microstripline and the left-hand end of the fourth microstripline are grounded.
