A filter circuit includes at least one series resonator having a first terminal and a second terminal, where the first and second terminals of the at least one series resonator are coupled to an input and an output of the filter circuit, respectively. The filter circuit further includes at least one shunt resonator having a first terminal and a second terminal, where the first terminal of the at least one shunt resonator is coupled to the input of the filter circuit and the second terminal of the at least one shunt resonator is coupled to ground. A polarity of the first terminal of the at least one series resonator and a polarity of the first terminal of the at least one shunt resonator are selected so as to reduce harmonic signal generation and other types of distortion in the filter circuit.
