Abstract

Two band-stop SERs (resonator A and resonator B) on silicon membrane were obtained and characterized. The frequency tunability domain of these resonators was between 3 GHz and 9.5 GHz ca. obtained by changing the dc magnetic bias field between H_appl = 0.02 T and H_appl = 0.34 T. The measurements of the S₂₁ parameter demonstrate a suppression of more than 20 dB of the high order modes, showing a good selectivity of this kind of resonator. The rejection ratio was better than -20 dB in the frequency domain from f = 3 GHz to f = 9.5 GHz for the resonator A and better than -20 dB between f = 4.2 GHz and f = 9.5 GHz for the resonator B. These results demonstrate the possibility to obtain microwave band-stop resonators supported on silicon membrane with high isolation and rejection ratios.
