Abstract
A non-reciprocal phase shifter including a transmission medium connected between first and second terminals and having a predetermined phase shift which is the same in each direction and an amplifier circuit connected between the first and second terminals for introducing its inherent phase shift in one direction and a phase shift in excess of its inherent phase shift in the other direction for establishing a non-reciprocal phase shift; and a circulator made from such a phase shifter.
