Differential pair impedance matching for a printed circuit board

Abstract

A printed circuit board (PCB), such as an antenna backplane, including a first conductor and a second conductor forming a differential pair, a first junction and a second junction connected to the first conductor and the second conductor, respectively, and a first impedance matching stub and a second impedance matching stub connected to the first conductor and the second conductor, respectively. The differential pair has a first impedance, the first junction and the second junction have a second impedance, and the first impedance matching stub and the second impedance matching stub match the second impedance to the first impedance. The PCB may have a connector that has differential pins joined to the first and second junctions, and the first impedance matching stub and the second impedance matching stub match an impedance of the junctions, pins, and a connector to the first impedance.
