Abstract :
A flux-drive nonreciprocal toroidal waveguide type phase shifter and its electronic drive circuit for use in phased array antenna systems are realized. The differential phase shifts versus the input current commands at three different temperatures are measured. A ROM table is constructed for each of the transmit and receive modes at these three different temperatures. The amount of differential phase shifts are controlled by a computer.<>
