Reconfigurable wideband high-frequency filter using non-reciprocal circulator

A non-transitory computer readable medium containing instructions that when executed cause at least one controller to:

• reconfigure a system comprising at least one non-reciprocal circulator and multiple reflective filter elements, each reflective filter element configured to receive a radio frequency (RF) signal from the at least one non-reciprocal circulator and to provide a filtered RF signal to the at least one non-reciprocal circulator, wherein the reflective filter elements comprise amplitude change reflectors configured to modify amplitudes of the RF signal at different frequencies;
• wherein the instructions that cause the at least one controller to reconfigure the system comprise instructions that cause the at least one controller to change a sequence of non-overlapping pulses in control signals provided to multiple switches of each non-reciprocal circulator in order to selectively control which of the reflective filter elements is conductively coupled to the at least one non-reciprocal circulator.
