Abstract :
A new type of dual-mode phase shifter which uses a transversely magnetized variable field section is described. The device retains the features of the conventional dual-mode phase shifter--low insertion loss, moderate amplitude modulation, adequate frequency bandwidth, simple physical geometry-- which allow it to be considered for use in two-dimensional scanning arrays. However, because of the transverse magnetizing field, the shorted-turn resistance is increased, which results in either reduced switching time or reduced switching energy when compared with the conventional dual-mode unit which utilizes a longitudinal magnetizing field.
