Abstract
A method of broadband phase shifting utilizing an unbalanced all-pass network topology has been developed. By taking advantage of the intrinsically matched characteristics of these networks, it is shown that multioctave response can be achieved by cascading of two or more similar networks. Utilizing this approach, an octave-band 4-b phase shifter has been realized. It has less than 18 degrees total phase error and better than -30 dBc carrier suppression when operated as a frequency translator.<>
