摘要： A variable capacitance device that achieves a desired capacitance even when factors causing varied capacitances are generated is configured such that a capacitance detection pulse signal is applied from a capacitance detection signal generation unit to a driving capacitor and a reference capacitor of a MEMS mechanical unit. The device voltage of the driving capacitor based on the capacitance detection signal and a driving voltage is applied to the inverting input terminal of a comparator. The device voltage of the reference capacitor based on the capacitance detection signal and the driving voltage is applied to the non-inverting input terminal of the comparator. The comparator generates a comparison output signal including “Hi” and “Low” values from the difference between these device voltages, and applies the output signal to a driving voltage generation unit. The driving voltage generation unit increases or decreases the driving voltage based on the comparison output signal.

摘要： A longitudinally-coupled-resonator-type surface acoustic wave filter includes three interdigital transducers provided on a piezoelectric substrate in the direction in which surface acoustic waves propagate. An interdigital transducer disposed at the approximate center among the three interdigital transducers of the longitudinally-coupled-resonator-type surface acoustic wave filter is divided into two parts substantially symmetrically in the propagation direction of the surface acoustic waves and the two parts are connected to balanced signal terminals, respectively. Left and right interdigital transducers of which the polarities are inverted relative to each other are connected to an unbalanced signal terminal to provide a balanced-to-unbalanced conversion function. A reactance component provided on the piezoelectric substrate, inside a package, or outside the package is connected to either of the balanced signal terminals.
