摘要
An apparatus comprises a bandpass circuit having a passband frequency range, wherein the bandpass circuit includes a first building block circuit including one ceramic resonator circuit element, wherein the building block circuit is a one pole filter circuit and a transfer function of the first building block circuit includes one finite transmission zero, and wherein a transfer function of the bandpass circuit includes the finite transmission zero at one of a frequency lower than the passband frequency range or a frequency higher than the passband frequency range.
