Multibit microwave memory readout from a ferrite-loaded stripline

Experimental multibit-microwave-memory-readout results obtained using direct-loaded and secondary-coupled toroidal ferrite memory elements in a strip transmission line are presented. Typical single-element readout response to a 4ns 650mA interrogation pulse was a bipolar 15ns ±21 mV signal using secondary coupling. The output-response magnitude decreases significantly as the number of memory elements loading the same stripline is increased.
