Abstract

In this paper, a new class of compact Chebyshev differential-mode (DM) bandpass filters with intrinsic common-mode (CM) rejection is proposed and demonstrated on λ/4 coplanar stripline (CPS) resonators with an improved unloaded quality factor (Q). The distinct advantage of the proposed λ/4 CPS resonator with higher Q than slotline resonator, together with intrinsic CM rejection of CPS line, can demonstrate that λ/4 CPS resonator is more suitable for the design of narrowband DM filter than others on slotline resonator. Then, the underlying physics why CPS resonator possesses higher Q than slotline resonator is numerically studied and further interpreted by the radiation loss. To facilitate the design process, an analytical design approach is introduced by using alternative J/K inverters and a tailored method is used to extract J/K inverter values with their associated effective electrical lengths based on their equivalent circuit models. Finally, two design examples, a second-order and a fourth-order DM Chebyshev bandpass filter, are designed and implemented, operating at the center frequency of 1.8 GHz with the fractional bandwidths of 6% and 19%, respectively. The simulated and measured DM/CM frequency responses match well with each other. The proposed DM filters based on λ/4 CPS resonators have demonstrated the claimed superior performances in terms of intrinsic CM rejection, improved unloaded quality factor, easy implementation of J/K inverter, inherent suppression of first DM harmonic, and compact size.
