ABSTRACT:
A magnetostatic wave device having a microstrip transmission line in conjunction with a YIG thin film biased for magnetostatic wave operation at a level where relatively lower power input microwave signals are highly attenuated up to a critical point past which the relative attenuation is greatly reduced. Such devices may be utilized as signal-to-noise enhancers in microwave circuits such as frequency memory loops.
