Abstract
A filtering power divider includes a first partial transmission line having a first electrical length, a second partial transmission line having a second electrical length, and a third partial transmission line having the second electrical length. The first, second, and third partial transmission lines connect to form a T-junction, and a sum of the first and second electrical lengths is ninety degrees. Thus, the first and second partial transmission lines cooperate to act as a quarter-wave transmission line. Similarly, the first and third partial transmission lines cooperate to act as a quarter-wave transmission line. Additional transmission lines may be connected to the first, second, and third partial transmission lines to implement a filter between an input port and each of two output ports.
