Thin-film RF noise suppressor integrated in a transmission line

A concept to integrate a thin-film radio-frequency noise suppressor in a transmission line is demonstrated by using Co/sub 85/Nb/sub 12/Zr/sub 3/ amorphous film with the microwire array structure. The ferromagnetic resonance loss generation at high frequencies is essential to realize this idea. The...

Zusammenfassung:	A concept to integrate a thin-film radio-frequency noise suppressor in a transmission line is demonstrated by using Co/sub 85/Nb/sub 12/Zr/sub 3/ amorphous film with the microwire array structure. The ferromagnetic resonance loss generation at high frequencies is essential to realize this idea. The degree of noise suppression is only less than 1 dB, which should be improved by optimum design to integrate the magnetic film.
