Abstract
This paper presents the dual-band filter design with pole-zero distribution in the complex frequency plane. Based on specifications, the poles and zeros of each passband can be distributed as desired, such as having poles on typical Butterworth/Bessel circle, Chebyshev ellipse, etc. This can provide different passband responses to meet different specifications of each band. In order to make more obvious the two passbands with different pole-zero distributions in the complex frequency plane, a filter is illustrated with the Butterworth response for its first band and the Chebyshev response for its second band. The simulation and measurement results are found to be in good agreement.
