New Dual-Band Band-Pass Filter Design with Enhanced Dual-Band Skirt Characteristics Conference Paper uri icon


  • A new frequency transformation concept is proposed to overcome the skirt characteristic of dual-band bandpass filters (BPF) caused by the conventional frequency transformation method. The new frequency transformation incorporates an extra frequency parameter to achieve additional rejection function in the high-frequency stop-band. To realize the concept, the dual-band BPF's resonators are modified based on their frequency responses. A new dual-band BPF was also designed with the modified resonators, fabricated and measured, and achieved desired enhanced skirt characteristic. © 2013 IEEE.
