Abstract :
In this paper, we have demonstrated the dual-band BPF using only two asymmetric SIRs, which has good dual-passband at 2.4/5.2 GHz. The measured results matched with the simulated results. The circuit size is reduced greatly about 45% compared with the conventional BPF at the same specifications. The proposed BPF structure can be extensively applied to the high performance mobile communication systems with multi-service response.
