Abstract
An arrangement of microelectromechanical resonators is
considered as
a filtering mixer for RF signals. The mixing is based
on the
second-order (nonlinear) force-voltage relationship of
capacitive
transducers that are used for electrical drive and
readout of the
resonator. Measured and simulated results are shown
for the first
prototype devices with a transducer gap of 1 $\mu$m.
With the gap
reduced to 100 nm by the time of the conference, the
approach is
expected to reach a good mixer performance for RF
frequencies up to
1 GHz. With 50 $\Omega$ source impedances the combined
insertion and
conversion loss is expected to drop below 10 dB. The
loss drop
further when impedance transformation is used to
raise the RF and LO source impedances seen by the resonar
r.
