A MEMS filter has an input layer for receiving a signal input, and an
output layer for providing a signal output. The MEMS filter also has a
first resonator and a second resonator coupled to the first resonator
such that movement transduced in the first resonator by the signal input
causes movement of the second resonator which transduces the signal
output. A method of manufacturing a MEMS filter is also disclosed. A
dielectric layer is formed on a base. A patterned electrode layer is
formed at least in part on the dielectric layer. The base is etched to
define a resonator structure. A method of adjusting a desired input
impedance and an output impedance of a dielectrically transduced MEMS
filter having transduction electrodes coupled to a dielectric film is
further disclosed. The method includes adjusting a DC bias voltage on the
transduction electrodes.
