Abstract
A new type of frequency selective signal‐to‐noise enhancer is described, which shows instantaneous bandwidths of more than 800 MHz at frequencies up to 4.2 GHz. The device consists of an epitaxial YIG film in contact with a narrow microstrip transmission line. Magnetostatic surface waves in the YIG film act as saturable absorbers of power from the microstrip line. Using a 26.6‐μm‐thick YIG film on a 23‐μm‐wide microstrip line of 21 mm length, resulted in a small signal (<−6 dBm) attenuation of in excess of 25 dB. The attenuation was reduced by 15 dB when the input power was increased to +10 dBm.Keywords
