Abstract

The present invention is for an apparatus and method of fast-switching a dual-toroid microwave ferrite phase shifter. A first circuit 23,24 is provided for controllably switching the ferrite in one of the toroids 9 between a saturated and partially saturated states. A second circuit 25,26 is provided for controllably switching the ferrite in the other of the toroids 12 between a saturated and partially saturated states. A control circuit 19 is provided for controlling the first and second circuits such that the ferrite in at least one of the toroids is maintained in the saturated state at any given time such that any desired phase shift may be achieved with only one switching operation for each toroid. The present invention provides new reference states such that there are two reciprocal phase states for any given phase state such that a reciprocal phase state may always be achieved with only one switching operation for each toroid.
