Abstract
Sequentially-Switched Delay Line (SSDL) can realize passive, nonmagnetic and non-reciprocal components for electromagnetic waves over ultra-wideband through the breaking of the time-reversal symmetry. A SSDL structure with six sections of transmission lines and five Single Pole Double Throw (SPDT) switches has been proposed as a three-port circulator in the literature. In this disclosure, a simpler structure consisting of only two sections of transmission lines with two switches is proposed, which can operate as a two-port non-reciprocal phase shifter (gyrator) with two SPDT switches, a three-port circulator with one DPDT switch and one SPDT switch, or a four-port circulator with two DPDT switches. Simulation results for one design at radio frequency demonstrated the expected non-reciprocal behavior from DC to 1.5GHz for aforementioned three configurations.
