Abstract :
The down-conversion performance of a multimodal microelectromechanical mixer-filter is improved over 30 dB by parametric amplification. The input signal is an amplitude-modulated signal with a carrier frequency of 0.5 GHz. The obtained amplification is shown to depend on the particular eigenmode in a predetermined way. Finally, a qualitative explanation for the behavior is given.
