Abstract
A microwave latching ferrite device is provided of the type associated with microwave transmission lines for effecting a phase shift or switching of the microwave signal being propagated. Driving means is provided for a latch winding of the ferrite device in the form of a blocking oscillator coupled between an input and the latch winding. The blocking oscillator includes a power transistor and a toroidal transformer coupled thereto. In response to a trigger pulse on the input, the blocking oscillator generates a single latch pulse on the latch winding, which is effective to change the degree of magnetization of the microwave ferrite device.
