Disclosed is a composition that can be used for producing surface covering. In particular, the mobile phone is operable in a W-CDMA mode and a band-reject filter comprising at least a series and a shunt acoustic-wave resonators is used to create a deep notch at the receive frequency band. Fasteners are coupled to the first end and a second end of the body section. The predetermined distances between the dummy features are specified as the minimum allowable value in respect of the manufacture of the elements. By such disposition of the first and second auxiliary electrodes, input signal light applied through a third port or a fourth port acts on the first main electrode prior to the first and second auxiliary electrodes. Additional clock accuracy may be achieved by adjusting the control word for process as well as temperature.
